Had the carb rebuilt by a reputable guy here in town. Followed the directions in the FSM to tune the carb and had it running great. Then I took it out on the highway and when I got off it went down to idle and glug glug stall!!! It starts right up with the throttle wide open and the float bowl is full to the top again.
I put all new fuel lines in and purged about 12 oz. of fuel before I connected it to the new carb. Also put in a new fuel filter.
Is it possible the new fuel pump is giving it too much pressure? Causing the needle and seat to stay open after i open it up?
