Front carb filling cylinder. Help!
Hi guys new to this site. Just bought a 93 Vulcan 750 with 10k miles. When I bought it, the bike ran, but ran poorly (got a good price on it.) I took off the carbs and got them professionally cleaned. The prior owner lived on a dirt road and didn't bother with air filters, so the carbs were full of sand. I reinstalled the carbs and the front cylinder fills with gas to the point that it hydrolocks the motor. I figured the carb mechanic must've made a mistake putting them back together, so I ripped the carbs off again and had him recheck them. He gave them a clean bill of health, so I reinstalled them. Same problem. I think it has to be some sort of vacuum problem. Where do I go from here? Sick of ripping off and reinstalling the carbs!
