And now for the rest of the story....
All two strokes need to be decarboned or decoked as part of regular maintenance. It's standard operating procedure. I can't tell you how often it should be done on your engine because it depends on the amount of gas you burn, the type of oil, and the operating conditions and temperature of the engine. You don't need to replace rings or hone the cylinder after decoking. You simply remove the carbon from the top of the piston and the combustion chamber with a scraper (not metal!) that doesn't gouge the aluminum. As long as the rings aren't stuck in the groove with carbon, you can leave them alone. The benefit is the engine runs cooler and is less likely to detonate and hole a piston. Too much carbon in the motor and the piston can also smack the head. If you don't feel comfortable working on your own motor, send it to RCignition and let him decoke it.




i would disagree with you once you remove the piston from head where the ring was seated is no more unless u can stop that ring moving at all unless you rehone and new rings you run the chance of blow by and thats a hole lot worse than carbon build up.
