This was just what I needed. Gokart hadn’t worked in a couple years and smoked terribly. Using youtube for tutorial, I swapped out the jug/piston/head and a couple other parts (didn’t need all of them so saved some for later needs). Kart runs as good or better than new.

As it says it fits Tomberlin Crossfires, not close. The cylinder outer diameter of the Howhit is 60mm. This cylinder is about 63mm in outer diameter. Quality seems o.k. and luckily I already have my case split but was not planning on this much work to make it work.
