Edelbrock Performer Carb

Anybody running a Performer on their small block?

There are two vacuum ports on the front of this carb. Which do you use for the vacuum advance?

I bought this carb at a swap meet so I didn't get an owners manual.

Also, are you using the temperature controlled hookup? It's a tower thing that keeps the distributor from getting vacuum until the engine is warmed up.

My engine seems to idle just fine, but it balks when you push the gas, and fires out the tailpipes when you back off while driving.

I'm thinking the vacuum advance is getting pulled to the retarded side instead of the advanced side.

Thanks,
