Slant six intake/carb question.

Are you getting good fuel supply from the fuel pump?
Yes sir. I actually replaced the tank, fuel sending unit, fuel lines, fuel pump twice ( first time was a bad pump), then replaced the fuel line from the pump to the carb and installed a clear filter. Everything fuel related was replace except cat, it was rebuilt. Also replaced brake lines and sealed to a duel reservoir master cylinder. I changed out the distributor to an electronic unit. I can not fire it off for weeks, walk out there and then the key and working 3 or 4 revolutions it will fire off and idle for a round 10 min. I can drive it around while it’s running good but when it gets warm I touch the throttle it just dies. I’ve got it running good enough to take to the dmv and drive around their parking lot for them to start the process of issuing me a “ for road use title”.
