i just recently bought another 85 rx7. its got the 12a bridgeport with racing beat intake and a 650 double pump holley carb with vac sec. trying to find the right carb for my application. i know racing beat has a kit but it was takin apart before i got the car and they just kinda made somthing work just so it would run. i dont have a place to hook up my oil linkage...

 

I don't understand. You can't have a double pumper with vac secondaries. It is one or the other. Double pumper means mechanical secondaries.

 

congrats.

 

ok then i guess i need a double pumper?? but it is a 650 holley though. some one said i need a 750 double pumper.
