216 engine, Rochester B 1 carb, rebuild kit on order but has not arrived yet.
Trying to start the engine, choke on, it will fire and run for 2 or 3 seconds and die.
I cleaned the carb up pretty well and blew out all the passages. 2 checkballs and seats are clean, the leather piston looks clean enough to work. Floats are set to 1-9/32 & 1-3/4 measured from the gasket.
There is no gasket on top or bottom of the thick insulator under the carb, but I sanded the insulator flat so it shouldn't be leaking much vacuum.
What should I do now ? I am at wits end
