And what is wrong with learning and doing it yourself? Take some old engines and experiment on them.
Here an interesting link all about 2-stroke engines:

Wow! Damn good information. Thanks, and with that information I'm sure I can improve on what I have been doing to these little engines. I have a question though; I notice that most of the top engine modifiers are putting this "red putty" (or something) in the crankshaft to better distribute fuel into the crankcase. How can I do that and what material are they using? Thanks.
