just to chime in here, its simple physics & generally accepted fact that 2 stroke engines run hotter with a lean mixture, thats everything from an RC car to a Motocross bike!
got you a link to an online guide to tuning that might help answer a couple of questions you might have
its not in my words but on a quick look through it appears to be mainly sound advice
take a peep [link=http://www.*********.org/cars_eng-tuning.htm]HERE[/link]
That's a useful guide thanks, but it doesn't actually explain the reason why leaning an engine makes it run hotter nor does your simple physics comment. Is it becase there is more heat genrated just because there is are more engine revs and so more combustion cycles or is there also more heat from friction due to less oil and poorer lubriation ?
