Re: need some carb help...I think
My 71 has similar issues. Mechanic told me I have a vac/air leak in the base of the carb. He offered to install a rebuilt QJ for $650. Nice guy. huh? When he set the timing and idle correct, it wouldn't even run without keeping my right foot on the gas while braking with the left. I've got a rebuilt one to put on now, but in the meantime I had to set the timing waaaaay BTDC to get it to run decent. Only problem with that is it slashed my mpg down to about 7 or 8. But at least I can give it gas and it takes off instead of bogging down. I'm hoping the new carb will improve everything.
