Re: Beginner Buying advice
I have a 66cc kit that I got off e-bay for $125 delivered, what I did to it was removed the cylinder and ported it, cleaned up the transfers and washed out the crankcase with fuel mixture. Then poured the mixture out onto a towel draped over a five gallon bucket to catch and debris or metal shavings. Its not hard to reasemble, the cylinder can be put back over the piston by squeezing the rings with your fingers. By the way I didn't find anything in my engine, or any of the others I've built.
Your results may not be the same,Greg
