Balancing carbs with vacuum guages

[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.

Any luck on carb adjustments?

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.

Hello everybody. I`m having problem like this as i think it`s the butterfly that i marked and could not slide back in. So i used another butterfly from a spare set of Carbs that i have. Anyway i went to start it up and it revved to 4000 RPMs and stayed there for about 5 minutes until i turned it off. It seems that the Carbs are stuck closed somehow. It is leaking what smelled like gas out the exhaust. The no.3 is ice cold and no.2 is luke warm as no.1 is hot...as is 4. The bike sat outside all winter -40 Temperatures. Where would one find a schematic for carb linkage maybe thinking i might of hooked up the linkage wrong amongst other problems. Thanks in advance any and all help will be appreciated.
