1964 220Sb Stalls when put in gear
About a month ago I bought a 1964 220S automatic-trans, dual zenith carbs, straight six, it leaked gas and didn't have brakes... but it ran...
So far I've seemingly gotten the master cylinder working (can't get a rebuild kit so I made my own seals) and bled the brakes, replaced a gasket in one of the carburetors so it no longer leaks gas. now it starts and stays running fine. I left it running a good 20 minutes in park without any help (revving) so it idles cold and warmed up.
The problem I'm having now is when its put in drive or reverse it jumps a little and stalls. Also, pressing the brake pedal causes the idle to drop and a hissing noise can be heard from inside the car.
I'm obviously leaning towards a vacuum leak but I don't know where to look.
