Balancing carbs with vacuum guages

Post by The Wolf »



Rebuilt the carbs on this 1975 Goldwing, and trying to balance them. Right side (1&3) they match up great. Left side are together too, but they are much less than right side, and I can’t match the left side to the right side. Barely touching the adj screw for # 2 and engine will die.
Just another weird problem ,removing the small screw on either 2 or 4 will kill the engine, but on 1&3 it’s not a problem. I’m thinking I still have a problem with carburetor. Any help much appreciated.

I've seen this happen if the butterfly on one carburetor is open much further than the rest. The bike will "run away" using the extra fuel/air from one cylinder. I'm guessing that's what you're seeing with cylinder #2. Maybe pull the carbs back off and visually set the butterflies first. There's a thread on here somewhere explaining what to look for.
