I tried removing the cylinder jug from my 1981 Honda NC50 and it's not budging. I used a rubber mallet, but it seems the mallet will get torn up before the jug comes off. Would carb cleaner cut through some of the crap holding the jug on? I don't really want to take the engine off the frame. What else would work? The rings on the piston are worn, causing a loss in power and eventually making the engine die. It's making the engine run rich and I don't want to seize the engine, so anyone know some other ways to get it off? And where to get some new piston rings that aren't expensive?
Thanks in advance!
