Vacume Problem?

Right now I don't have it hooked up at all, but I don't know whetre a ventrus is. I had it hooked up to a small port in the front of the carb

My carb is a 750 with vacume secondaries. The cam is a crane came, but nothing crazy. I have the dimensions on another post that I have somewhere, but not sure where right now.


That isn't really what the engine is doing. It will idle ( with vac hooked up) you can smap the throtle ( with vac hooked up)
You can't slowly increase the throtle, or hold it at any thing other than idle ( with vac adv hooked up.

With everything pluged it works MINT!

I talked to me mechanic and he said to just plug it, and I don't need it. He is a sertified mechanic for several years. Not just some back yard mechanic.
