so i put a 216's rochester B, on top of a 235 BC throttle body, on to a 56 235 manifold. it seems like when I get it going, the idle jumps WAAAAAAAAYYYYY high , then the engine stalls.

I have not changed anything inside the 216 carb, I have a 235 carb, but i havent tryed it out cause i didnt have a air cleaner for it. do i need to change the power piston or metering jet? is it doing this because I hooked my vac advance to the tube on the bc? the bc throttle body didnt have a vac advance connection.

I screw in the idle mix all the way, backed out 1.5, and tryed to back out the idle speed. it will seem starved if i go back to far, then if i screw it in a lil bit, the engine will run but the idle jumps SUPER high after about 2 seconds, then it either stalls out it i kill the ign cause it sound to fast

here is a clip of it. the first time its puttering for a bit. The 2nd time i start it at 45 secs, it takes off really high then stalls
