The carb is a 650 double pumper from the 90s. It's old but ran great on the other car. Also I have timed it as best I can without a dial back light, also the power valve is brand new and a 3.5". I get around 7-7.5" of vacuum at idle. I know the cam is completely absurd, I dunno why the guy I got the motor from put it in. I've also tried a brand new eddy 600 on the car and have the same problems fwiw
