I bought a c750 cb750 a few weeks ago. Since purchased it has stalled at low rpms when coming to a stop. I filled the tank with premium treated with seafoam, changed the oil and changed the plugs. Took it for a ride then noticed gas dripping from the overflow on two of the carbs. Replaced needles and seats on all 4 and went for a ride. Noticed gas dripping again. Went to take off and could not accelerate. The engine would rev up in neutral but would bog out in first. I checked the pipes and noticed #1 was barely warm and 2,3,4 were scalding hot. Messed around in the parking lot for a bit and it started running better. Managed to make the 5 mile ride home, checked the pipes and #1 was still just warm. I have spark, switched wires with 1 and 4 and 1 still didn't heat up. I thought fuel maybe so I rebuilt the carbs, they don't leak anymore(think I set the floats wrong the first time),but still #1 wont heat up. Thanks in advance for the help
