318 Engine stumble

I’m going to go through the carb and blow out all the air bleeds and wells. All the ports on the primary and secondary. One thing I have not adjusted on this used carb is the accelerator pump. I went though and memorized the Holley flow diagram so I have a good idea where and how it’s working.


Then test the coil and ballast resistor like you said. The coil is a blaster 2 msd and the ballast resistor is new so they both should be good. Neither have even 100 miles on them.

Could a bad condenser cause a high dwell?
As far as the dwell goes. What about skipping the feeler gauge and just opening the points up until the dwell hits 32.

What I’ve been doing is adjusting them. Putting the whole thing back together and idling the car. The dwell shows 41 at .017.
So maybe open them up to .020 and see what that does.
The cam block doesn’t look worn but I don’t know how to get spec or tell. The distributor is old 1968 and may be original to the engine.
I do want to put the elsectronic set up in but I want to understand these points. The shaft play seems fine
