2019 kymco mongoose 70 carb issues
« on: July 11, 2024, 01:03:49 AM »
After dealing with carb issues from the dealer decided to replace with pz19 carb from china. Previous carb was autochoke, new one is manual. After install, cranked fairly easily but is running like it’s wide open. This model has a CVT transmission so no way to be in neutral and only way to keep it from running away is engaging the parking brake. The transfer case seems to get very hot trying to be geared down. I have chalked the front tires and put the rear axel up on a block to work out the carb kinks. I have turned the fuel/air mix screw in and out whilst doing the same with idle screw and no change. The throttle cable was loose so doesn’t make me think it’s cable tension causing the wide open rpms. Needle position would appear to be in the only option that’s available for the carb needle. Any thoughts would be appreciated.

The PZ carbs from China are ok, but there are two screws not one to adjust, one is hidden under the bolts that attach to the card manifold off the barrel.... they rarely arrive "pre-set", it may not be the problem but worth a look.
