There is a ton of information on this subject available, just google crankshaft balancing and wade through the hits. On an echo I wouldn't advise much in the way of changes, though. They are pretty...

Shindaiwa c4??

Anyone tried one of these engines? Poppet valves, compression charged with two stroke mix. They sound funky and make decent power.
