Just bought a rebuilt carb. Started it up ran rich so tried to adjust it with a little success. When I shut it off, alot of gas came pouring out the drip hole on the bottom of the carb. It still runs rich, looked at float and setting and everything seems fine. Needle and seat work and look good. Could the gas really be a result of it running that rich? Also was checking my throttle linkeage and noticed on the end of the throttle shaft the hole for the throttle driver next to the economizer is not there, hence the throttle driver (part no. 21235DA) is not there. Would this cause any problems, figure if it was on originally there probably is a purpose right?? Thanks for the help
