Tad hard to start......pretty sure fuel issue

You need to put the regulator after the carb and run a return from the regulator back to the tank. I am having the same problem. The way you could test is turn the pump off before you shut off the car. Then start the car before you turn on the pump.

What happens with todays fuel is it heats up at the carb and doesn't allow the needle to keep the carb. from over filling. The return will allow a constant flow of cool fuel and the carb will work properly.

Like I said my car does exactly the same thing. My freinds did the same and he corrected it the way I mentioned above.

You can see in the pics below that I even replaced my carb. My fuel line allows the regulator after the carb. I do not have the return hooked up on these pics but I will this year. the regulator will be placed in the line after the carb to keep the fuel moving and not dead end at the carb
