yeah the sportwerks are cheap but actually good carbs, ive seen many people get them and it makes their engine come alive... i fixed my picco carb with some JB weld around the seam where the composite and aluminum part meets. ever since i did that i had ZERO issues.

none of those carbs will work, ive tried them. the only carbs i know of that work are jammin JPX, ofna JL (but they are pretty much the same carb as you have), Orion Alpha and sportwerks. there are probably a couple more but i havent heard of anyone using anything else.
