If you’ve been driving for any time, you’ve probably experienced engine kickback. This is when the engine suddenly lurches back and forth, usually as a result of acceleration.
While it can be unsettling, there are ways to fix engine kickback so that you can get back on the road without incident. This problem can be dangerous and cause accidents, so it’s important to know how to fix engine kickbacks.
Summary: Engine kickback is a dangerous mechanical issue that can occur in internal combustion engines. It is caused when the spark plug fires at the wrong time, usually due to a lean fuel-air mixture or engine timing problems. To fix this issue, check the air filter and spark plugs for dirt or damage, ensure it has the right fuel-air ratio, and check that the engine components are properly timed.
10 Reasons That Causes Engine Kickback
1. Incorrect Ignition Timing
The timing of the spark plug firing in the engine is critical. If it’s set too early, the piston will have already started its downward travel and the compressed air/fuel mixture will be forced out of the cylinder past the open intake valve.
If your engine pings or knocks, it could be seriously damaged. Pinging or knocking happens when the air/fuel mixture in the engine isn’t burned completely, and can cause the piston to knock as it reaches the top of its travel.
2. Worn Spark Plugs
If a spark plug is old or damaged, it might not work right and cause the engine to kick back. This happens because the spark plug starts the fire that ignites the mixture of air and fuel in the engine cylinder. If the spark plug isn’t working well, the mixture might ignite too soon and cause the engine to kick back. You should put new spark plugs in if the old ones are worn out or damaged.
3. Dirty Air Filter
If your air filter is dirty, it can cause the engine to “kick back.” This happens when the air/fuel mixture ignites too early, and it can damage the engine. Be sure to replace the air filter if it is dirty.
4. Incorrect Fuel
If you use the wrong type of fuel in your engine, it can cause the engine to kick back. This happens when the air/fuel mixture ignites too early. To avoid this, you should always use the type of fuel recommended for your engine.
5. Defective Carburetor
A defective carburetor can also cause engine kickback. A defective carburetor can cause the air/fuel mixture to ignite too early and cause engine kickback. If you think that your carburetor may be defective, you should have it checked by a qualified technician.
6. Dirty or Clogged Spark Plugs
Dirty or clogged spark plugs can also cause engine kickback. Dirty or clogged spark plugs can prevent the spark from igniting the fuel in the engine properly. This can cause the engine to backfire or kick back. If your spark plugs are dirty or clogged, you’ll need to clean or replace them. Bad Gasoline
Gasoline that is old or has water in it can also cause engine kickback. If the gasoline in your lawn mower is old, it may not burn as well. This can cause the engine to backfire or kick back. If there is water in the gasoline, it can prevent the spark from igniting the fuel properly.
7. Incorrect Spark Plug Gap
The spark plug gap is the distance between the electrode and the spark plug’s tip. If the gap is too wide, the spark will have difficulty jumping across it. This can cause engine kickback. To fix this, you’ll need to adjust the spark plug gap.
8. Defective Coil
A defective coil can also cause engine kickback. A defective coil can prevent the spark from igniting the fuel in the engine properly. This can cause the engine to backfire or kick back. If you think that your coil may be defective, you should have it checked by a qualified technician.
9. Engine Misfire
One possible reason your engine is kicking back is because of an engine misfire. When the air and fuel mixture in the engine combustion chamber is not completely balanced, it can cause the engine to “knock” or “ping.” This happens when the air/fuel mixture detonates prematurely, causing the piston to bounce up and down. If this problem is not corrected, it can cause serious engine damage.
10. Exhaust Gas Recirculation Valve Not Working Properly
The exhaust gas recirculation (EGR) valve is responsible for recirculating a portion of the exhaust gases back into the engine. This helps to reduce emissions. If the EGR valve is not working properly, it can cause an engine knock. You should have the EGR valve checked if you think it may be defective.
10 Effective Ways on How to Fix Engine Kickback
1. Check the Air Intake System
The first step is to check the air intake system. If there is any dirt or debris in the system, it could be causing the engine to kick back. Clean out the air intake system and see if that fixes the problem.
2. Adjust the Carburetor
If the air intake system is clean and the engine is still kicking back, the carburetor could be a problem. Adjust the carburetor so that it is set slightly higher than before. This will help to prevent the engine from kicking back when you try to start it.
3. Replace the Spark Plug
If the spark plug is old or damaged, it could be causing the engine to kickback. Replace the spark plug with a new one and see if that fixes the problem.
4. Check the Ignition System
If the engine is still kicking back, it could be a problem with the ignition system. First, check the ignition system to make sure that all of the connections are tight and there is no damage to any of the components.
5. Clean the Fuel System
If the fuel system is dirty, it could be causing the engine to kickback. Cleaning the fuel system can help to fix the issue. First, disconnect the fuel line from the carburetor. Next, remove the fuel bowl and clean it with a carburetor cleaner. Finally, reattach the fuel line and test the mower.
6. Adjust the Valves
If the engine is still kicking back after doing all of the previous steps, you may need to adjust the valves. The valves control the amount of air and fuel that enters the engine, so if they are not set correctly, it can cause the engine to kickback. You can adjust the valves by turning the adjustment screws on the top of the valve cover. Be careful when doing this, as too much adjustment can damage the engine.
7. Replace the Fuel Filter
If the engine is kick backing due to a clogged fuel filter, replacing the fuel filter should fix the problem. Be sure to replace the fuel filter with an OEM part or one designed for your vehicle. Do not use a generic fuel filter as this may not fit properly and could cause further problems.
8. Check the Valve Clearance
If the valve clearance is off, it can cause the engine to kick back. You can adjust the valve clearance with a wrench. First, find the right size wrench. Next, loosen the bolts on the cover of the engine. There should be one at the top and one at the bottom. Now that the bolts are loose, you can turn the wrench to adjust the valve clearance. Be careful not to over-tighten the bolts.
9. Change the Defective Coil
Changing the coil should fix the problem if the engine is kicking back due to a defective coil. A defective coil can cause the engine to misfire, which can lead to kick back. Be sure to replace the coil with an OEM part or one designed for your vehicle. Do not use a generic coil as this may not fit properly and cause further problems.
10. Try a Different Brand of Fuel
If you have tried all of the previous steps and the engine is still kicking back, you may want to try a different fuel brand. Not all fuels are created equal, and some brands may work better in your vehicle than others. Try using a different fuel brand and see if that fixes the problem.
Tips to Prevent Engine Kickback in the Future
- Use a chainsaw with a low kickback chain.
- Be sure the chainsaw is properly sharpened.
- Use the correct guide bar and chain for your saw.
- Be cautious when cutting small diameter branches that are under tension.
- Don’t try to cut too much at once; make several smaller cuts instead of one large cut.
- Use a chainsaw with anti-kickback features such as an inertia-activated chain brake.
- Be sure to follow the manufacturer’s recommendations for maintaining your saw.
- Kickback can also occur if the saw becomes bound in the cut, stop cutting, and release the pressure on the saw.
