[dan650plus]

Have a 79 GS750E I just picked up some one took the air box off and put on pod filters. M y question is it has 3 vac lines they are on #1#3#4. #1 is onthe petcock but has no vacuum #3 has vacuum and #4has no vacuum. 3 and 4 are just hanging down and the petcock does not work unless i hook it to #3 .where do they all go?

Carburetor #3 has the vacuum port which goes to the petcock. The other two are vents. They can stay open, or put a piece of hose on them open on the other end. They need to vent to open air.

Cliff's pictures show a CV carb, on those the #2 carb has the vacuum port.
