I can’t tell you how frustrating it is when your lawn mower starts acting up in the middle of a job. It’s even worse when you’ve been using the same model for years and know that it doesn’t have any major issues.
In my experience, there are a few common reasons why a lawn mower might start then die soon after.
One possibility is that there’s something wrong with the spark plug. Over time, they can get gunked up and stop working properly. This is an easy fix though; simply clean or replace the spark plug and try again.
If that doesn’t work, another potential problem could be an issue with the gas line leading to the carburetor. Be sure to check for any cracks or leaks in this line, as well as making sure there isn’t dirt or debris clogging it up.
Lastly, if your mower has been sitting for awhile without being used, old gasoline can cause problems starting up again too

Bad or Old Fuel in Your Mower
If you have a Bad Boy mower, it’s important to be aware of the potential problems that can come from using ethanol fuel.
Ethanol-based gasoline is now the norm at most gas stations, but this alternative fuel can cause some issues for your Bad Boy mower if you’re not careful.
The main problem with using ethanol-based gasoline is that it breaks down much quicker than regular gasoline. This means that the fuel might start to degrade as quickly as 30 days after purchase.
Because ethanol draws moisture from the atmosphere, this mixture of water and alcohol will eventually settle to the bottom of your fuel tank.
When this happens, running your mower on this lower-quality fuel can damage engine components due diligence isn’t taken care off before hand..
So what should you do if you want to use Bad Boy lawnmowers? If possible, only fill up your tank part way so that you’ll use all of the gas before it has a chance to break down too much.
You should also try to avoid letting your mower sit idle for long periods – even just a few days can allow enough moisture into the system to cause trouble when combined with Ethanol .
Finally, consider purchasing a higher quality product designed specifically for vehicles that will be sitting unused for long periods or those operating in extreme conditions like cold weather

If you find that your fuel is stale, use a fuel siphon to empty the tank. Put fresh gas in the tank. Use a fuel additive to stabilize your gasoline, reduce moisture content, and clean your fuel system.
I apply a substance called Sea Foam Motor Treatment. This tutorial explains why I add sea foam to every gas tank.
Plugged Air Filter in Your Mower
It’s crucial to always use an air filter when operating your Bad Boy lawnmower. A filter is necessary to keep dirt and other particles from getting into the engine.
A significant amount of engine damage from dirt particles can result in a high repair price. Checking and cleaning the air filter should be done on a regular basis, according to manufacturer specifications.
The carburetor is another crucial component of the mower that maintains the correct air supply. The carburetor can both let too much air in and restrict too much air.
According to manufacturer standards, theair screw on carburetors needs to be adjusted to a precise value in order
to allow the ideal amount of enter. If this is configured incorrectly, you’ll run into issues with initiating fuel combustion correctly.
Our Fix
Our fix is to clean the air filter in your Bad Boy mower. This will help remove any dirt or debris that may be clogging it and improve its performance.
According to the directions for the type of air filter you have, remove it from the housing and clean it with a dry towel.
If you have a paper air filter element, be sure to follow instructions on how to properly clean it so as not destroy the material. The same goes for foam filter elements – ensure you know what cleaning products are safe to use without damaging them.
Once everything is wiped down and rinsed off, replace the airfilter back into its rightful place in order to prevent any further issues!
Plugged Fuel Filter on Mower
If you have a Bad Boy lawn mower, it’s important to know about fuel filters and how to keep them clean. A fuel filter is used by your mower to filter the gasoline and prevent dust and other contaminants from getting into the engine.
Over time, though, sludge and gummy deposits can build up in the filter and cause problems. To avoid most fuel filter issues during the mowing season, it’s best practice to replace your fuel filter every year.
While some lawnmowers have replaceable fuel filters attached to the gas line, other models have filters that are housed inside the gas tank. If you’re unsure of where yours is located, ask your manufacturer.
Some manufacturers recommend changing or cleaning your fuel filter more often than once per year – so be sure to follow their recommendations as well.
Our Fix
If you’re having issues with your Bad Boy mower, one thing you can check is the fuel filter. If it’s clogged, simply replace it with a new one – they usually have an arrow on the side to indicate which way is up. This simple solution could save you a lot of time and money down the line!
Clogged Fuel Lines on Your Mower
Bad Boy mowers are known for their durability and reliability. However, even the best machines can have problems from time to time. One common issue is clogged fuel lines.
This can happen when old fuel leaves behind gummy deposits that restrict or block the flow of fuel. As a result, your Bad Boy may die in the middle of mowing your lawn.
If you suspect that your fuel lines are clogged, the first step is to shut off the flow of gas using the valve at the base of the tank. Then, inspect each section of fuel line, looking for any restrictions or blockages.
You may need to use pinch pliers to crimp sections of Fuel Line in order to stop Flowthrough grill places .
If this doesn’t fix problem , it’s likely that Your carburetor needs cleaning . Carburetors tend to get dirty over time and this can cause all sortsof performance issues , including poor starting , stalling , and loss Of power while mowing .
Our Fix
You can check a few things to try and fix the issue. First, check any sections of fuel line or the fuel filter that might be obstructed – this could be preventing adequate fuel flow from the line into the container.
Once you’ve narrowed down the blockage to a specific section of fuel line, stop the flow of gas and take that section out of the mower.
To help clear any obstructions, spray carburetor cleaner into the line before blow compressed air through it – repeating as necessary until cleared. If you’re unable to remove an obstruction this way, install a new section of gasoline line in its place.
Mower Carburetor is Dirty
If your engine isn’t running as smoothly as it used to, one possible culprit is a dirty carburetor. Carburetors mix air and fuel together in the right proportion to create combustion, so if it’s not doing its job correctly, neither will your engine.
You can clean your carburetor with some elbow grease and patience, but depending on how bad the deposits are, you may need to replace them entirely. Either way, giving your carburetor some attention should help get your mower back up and running!
Our Fix
If your lawn mower isn’t working properly, it might be time to clean the carburetor. This guide will show you how to do just that in a few simple steps. All you’ll need is some spray carburetor cleaner (aerosol) and a screwdriver. First, remove the air filter and then unscrew the bowl from the bottom of the carburetor.
Inside, you’ll find the float needle – this controls fuel flow into the carbohydrate chamber. Use your brush or cloth to clean all surfaces inside before reassembling everything and putting your air filter back on. Now try starting up your lawn mower again – it should be running like new!
Plugged or Broken Cooling Fins
Keeping the cooling fins on your engine clean and unobstructed is important if you own a Bad Boy mower. These fins help to circulate air around the engine block and cylinder head, keeping them cool. If the cooling fins are plugged or broken, they can impede air flow and cause your engine to overheat.
Our Fix
To clean the cooling fins on your Bad Boy mower’s engine: first shut off the power and allow the motor to cool completely; then remove any debris that may be blocking airflow; finally, use a brush or compressed air to remove any dirt or grime build-up.
Inspect regularly for damage so that you can replace damaged parts as necessary. Keeping your cooling system clear of obstruction will help ensure peak performance from your mower’s engine.
Insufficient Engine Oil Level
If the engine oil level in your Bad Boy mower is insufficient, it can lead to a number of problems. The first and most obvious problem is that the engine will not have enough lubrication, which can cause damage to the pistons or other moving parts. Additionally, an insufficient oil level can cause overheating, as less cooling liquid will be present.
Finally, if you continue to operate your mower with an insufficient oil level, serious engine damage may occur, requiring expensive repairs or even replacement. To avoid these issues, always check your engine’s oil level regularly and top up as necessary – but be sure not to overfill!
Too Much Engine Oil in Your Bad Boy Mower
If you add too much engine oil to your Bad Boy lawn mower, it can develop crankcase pressure which can cause the mower to overheat and stop working.
You should check the engine oil level using the dipstick and if it is above the full line, you will need to drain some of the oil out through either the filter or drain plug.
Too Little Engine Oil in Your Bad Boy Mower
If there’s too little engine oil in your Bad Boy mower, it can cause some serious problems. Not only will the lawn mower not run as efficiently, but it could also overheat and shut down.
To avoid these issues, make sure to check the engine oil level frequently and add more oil if necessary. You can remove excess oil by draining it through the plug or filter, or using an evacuator or turkey baster.
Bad or Dirty Spark Plug on Your Mower
If you have a Bad Boy mower, keeping the spark plug clean is important. A dirty or fouled spark plug can cause your mower to operate sluggishly and even die. You should check your spark plug regularly to make sure it’s in good condition.
Our Fix
To do this, simply remove the spark plug with a socket and pliers (being careful not to damage the wires) and examine it for dirt or cracks. If necessary, gap the plugs according to manufacturer specifications.
You may also want test the plugs by holding them against a metal component of the engine while someone else pulls on the starter rope – if they’re working properly, you should see strong sparks coming from each one .
Replacing damaged or worn out plugs as needed is crucial for keeping your Bad Boy running smoothly .
Bad Ignition Coil
If your Bad Boy mower is giving you trouble starting up, it may be due to a bad ignition coil. The ignition coil is responsible for providing the spark plugs with the voltage they need in order to create a spark.
If the winding on the ignition coil becomes separated, it can cause the voltage to drop and prevent the spark plugs from firing correctly. This can eventually lead to your mower shutting down completely after running for awhile.
To avoid this problem, make sure to check the condition of your ignition coil regularly and replace it if necessary
Our Fix
Use an ohm meter to look for continuity breaks in order to spot a faulty ignition coil. If an ignition coil break is discovered, replace it.
Choke is in the Wrong Position
The choke on your Bad Boy mower is in the wrong position and needs to be corrected. The choke is used to allow more fuel and less air into the engine cylinder, which helps create a combustion when starting a cold engine.
Our Fix
To fix this problem, simply adjust the choke lever to allow more airflow after the engine has warmed up. This will ensure that your mower stays running smoothly all season long.
Faulty Mower Gas Cap or Rollover Vents
Your Bad Boy mower may have a problem with the fuel cap or rollover vents not functioning properly. This can cause air to enter the fuel tank, which prevents gas from reaching the engine and may cause the mower to shut off.
To determine if this is the issue, take off the fuel cap and see if starting and running it for a period of time solves the problem; put back on fuelcap afterwards to test.
Our Fix
The rollover vents on the fuel tanks or the gas cap may be used to vent your fuel tank. Replace the fuel tank vent on your Bad Boy mower by determining its kind.
If you have a type 1 fuel tank, you will need a new Type 1rollover vent. These are available at most hardware stores. For Type 2 tanks, you’ll need a new gas cap with a built-invent valve.”
Plugged Mower Deck
If your Bad Boy lawn mower’s deck is plugged with debris, it can cause the blades to stop spinning and the engine to overheat. This is because it takes more effort for the engine to turn the blades through a cluttered deck.
As a result, your lawn mower may not operate as effectively and could break down completely. Be sure to clear any debris from your mower’s deck before using it again to avoid these issues.
Our Fix
Keep your deck clean by regularly scraping it to avoid this from happening. The grass clumps and sticks to your mower deck when it’s wet, so avoid mowing in those conditions.
If you want to reduce grass buildup, you could try using a deck spray. Deck sprays can reduce the amount of debris gathering under the deck, but they are not a magic solution that stops all buildup.
