Thermoquad fuel leak

When the car is not running and fuel is squirted on the shaft it will find its way out. On a running motor the problem is almost non existent. I rebuilt that carb for him last year. I must have judged that shaft to be ok. The TQ has a lot of shaft hanging out there unsupported, so any wiggle is drastically exaggerated out at the end. Unlike a Holley. However had I heard from him about this issue, I would have resolved it. And still will, gladly. But i don’t think that it is sucking much air, last week the OP posted a concern of a possible rich condition. Then that thread just died.

Well, I've said as much myself in other posts regarding shaft wear. ....or more appropriately, shaft BORE wear. The incoming air fuel charge will take the path of least resistance and that sure as heck AIN'T through the throttle shaft bores. lol
