    Need help with idle

    I just got my bike back up after a few years and it runs fine. However when I pull the left lever and stop the bike so it idles, the engine gets incredibly loud and starts vibrating hard.

    Hey guys just wanted to ask what carb setup you guys recommend for a 48mm bore x 41mm stroke engine I'm building. The ports are 40mm. Would a 19mm delorto clone with a #90 jet be good? it is a iron lined cylinder.

    Belt drive 2 stroke budget build

    I've just been going through ideas I had after looking at a few old weedeaters, of course these engines are very small I wouldn't go under 25cc and pedalling would be neccesary. If you could attach a pulley to the shaft while still keeping the pull start then you could build a mount for the...
