yeah they are pretty good engines, i've heard a lot of good things about these, but you may want to check out firepowerminis.com Terry has some yx140's with carb wiring etc....for around $329 I believe.

JW, why does that engine only have a 22 mm carb on it? Shouldn't it have a 24 or 26 mm on it?

Numbers game... It would likely run better on top with a bigger "true" 26mm carb, but the "22" is the same as other oval venturi 24-26's, and they run fine. Parts and jets are easily available. Other than needing a short screwdriver to adjust idle fuel mixture, they're a fine carb. The outlet is 26 as is the manifold. Just the venturi is smaller. TB 20mm has a 20mm outlet, much smaller oval venturi, and make great power, have good response.
