Unless you want to go OEM (Minoku?) I would consider rebuilding it. I tried one of the Amazon knockoff carbs and it worked only ok. Wound up rebuilding the OEM one and that worked better.

The Amazon knockoffs are cheap enough that they may be worth taking a chance, your luck may be better than mine. The good thing is you will have it even if you end up rebuilding. I robbed a diagram off of the Amazon carb when I rebuilt my OEM carb.
