You might need to shim starter, once the engine is warm/hot, thermal expansion pushes the starter away from the flywheel, bet cold engines have it closer, possible it is close enough to almost jam.

I would also check voltage at starter when cranking, sometimes I even just run another fresh battery and cord to starter to see if it is possible you have a weak battery.

Holleys sometimes have issues with powervalves, they leak, they don't work. A stumble that is solved by slowly easing into the throttle sounds like not enough fuel, and actually another possibility for the slow cold start-leaking fuel from the nozzles of the carburetor after shut down. Less likely then the above mentioned starter issues, but still worth mentioning.

1967KaiserM715 makes the most compelling case, especially after the heat factor comes into play.

I have seen starters shimmed over the years, can't hurt to try.

Unplugged the distributor today and it turned over more quiet, fast and smooth than anytime I've ever had it.

That timing?

did you ever set the timing with a timing light?

When the starter went tits up, I had a shop put it in. Guy there (30+yr ASA mech) said he timed it with the light and dialed it back to 10 deg adv (from 22). Supposed to be dry tomorrow - I think I have it close to TDC - have a tool showing up via USPS tomorrow to confirm its right on. At first glance, the distributor looks to be out - like clockwise an inch too far. I want to pull it out and start over - make sure its on. I have a light will dial it in myself afterwards.

I took the cap and rotor out today - they're basically brand new. I also pulled the plugs and I think (no joke) they may be original.....100k. Gaps were all over the place .020 diff between some. Got new ones in. Would also like to get rid of the Cali emissions that are on it - anyone know the thread size of the pipes that go into the exhaust mani? Will need a plug.

Got everything timed today - at around 11-12 advanced. Runs good but still starts hard. For shts and giggles I took the battery out (<year old Interstate) to have it checked under load.....it failed. 1-2 bad cells. Maybe that was it? Dunno yet.
