Re: carb overflowing

Rebuild it, or have it re-built. Float is stuck.

Re: carb overflowing

Total re build time; the gunk carb cleaner is expensive.
But cheaper than the shop.

Re: carb overflowing

I was looking at carb kits online the only thing I have not put new in it is the power jet thats why i was wondering if it could get bad and let gas pour thru the jets at the bottom of the throttle body.

Thanks

Re: carb overflowing

The Float could also be Too Heavy.....
