- Incorrect fuel mixture: If the fuel mixture is too lean, it can cause the engine to run hot and detonate, which can damage the pistons. Make sure that the carburetor is properly jetted and that the air filter is clean.
- Low octane fuel: Using fuel with too low of an octane rating can also cause detonation and damage the pistons. Make sure to use fuel with at least the recommended octane rating for your engine.
- Worn piston rings: Worn piston rings can allow oil to get into the combustion chamber, which can cause the engine to run hot and detonate. Make sure that the piston rings are in good condition and that they are properly seated.
- Damaged piston: A damaged piston can also cause the engine to run hot and detonate. Make sure that the pistons are in good condition and that they are not cracked or chipped.
- Overheating: If the engine is overheating, it can cause the pistons to expand and seize, which can damage them. Make sure that the cooling system is working properly and that the engine is not running too hot.
If you have checked all of these things and your engine is still blowing pistons, it is possible that there is a problem with the engine itself. You may need to have a professional mechanic take a look at it to determine the cause of the problem.
