theres a stall 2 1500-2000 rpms then it sounds ported after that i cant get past 4.5k

but when i hit the secondaries boom its a rocket

carb rebuilt no vac leaks i can find
fuel mixture changes nothing
timing does nothing low fuel pressure or insufficent plugs i really need help its been driving me nuts the past 2 weeks the car is undriveable

Did this start after the carb rebuild?

Any other changes?

Or

Just out of the blue.

why did u have to swap engines? it sounds like it's running on one rotor. double check the coils, plugs, and wires. if u pull the leading wires one at a time while it's running u'll find out which rotor isn't firing.

But since the car is a rocket once he opens the secondaries it kinda throws a wrench into that theory...

I would pull the fuel jets and make sure you don't have a clogged jet.
