Okay, here's a question I need some input on...a while back I posted a problem I thought I might be having with fuel delivery...part of that problem has been solved, but not all..after installing a new tank and fuel pump I'm still having problems starting the car from a cold start..will crank and crank and crank and nothing happens...If I put gas down the carb and crank It for a while it will start and stay running...shut it off and try to start again...no go...since the fuel pump is new I'm thinking it might be the fuel pump rod...Also shouldn't there be some gas left in the carb even after shutting down ? The bowl is supposed to retain some gas...correct ? Also after the engine warmed up I pulled the vacuum hose off the distributor to check the timing and the engine died immediately...

before you crank it, under the hood jerk the throttle several times & see if the AP squirts. after you shut it off from running, under the hook jerk the throttle several times & see if it squirts. are you on ported or manifold? if you clamp the hose then pull it off the dist will it still die?

thank you for the input...fuel pump was delivering good amount of fuel after I disconnected the line to see what kind of pressure I had...I figured there must be some sort of restriction in the carb,,,took it apart and sure enough there was a lot of junk inside the throttle pump area and other parts of the carb...went right through it cleaning out all the components with carb cleaner...put it back together...car starts now without putting gas down the carb...I think the problem has been resolved...

you need to change the vacuum hose to the distributor from having manifold vacuum to ported vacuum on the carb, which will require resetting the ignition timing like all Mopars muscle cars came with wrench scope
That change should make your car run better ,especially at light part throttle cruising scope up
