Ive only used the cheap Chinese carbs on a honda recon and they work well for a couple days then begin to fall apart, leak gas, etc. and the quad begins to run like garbage. The body does not hold up well either, the threads on the throttle cable strip out and cause the slide to pull up so the engine runs on full rpm, has caused a number of accidents including rollovers on this particular 4 wheeler. We ended up using parts like the floats and jets to fix up the original carb body, but it’s probably more advisable to rebuild it.
