I have the carburetor off and all apart. Prior to running it sat 43+ years.... Since I did not see any gas "squirt" I am going to check the power piston and pump. Must be semi or blocked somewhere. I do have a second carburetor (Rochester model b) and might go through that one and run it to see if problem gets eliminated.//// It should be noted I cleaned and rebuilt the carburetor after it sat for 43 years.
Reading up on the Rochesters, for some reason it's not uncommon for people to leave out the ball check valves, so on the accelerator pump all you do is pump fuel back into the bowl.
