So...another issue. Now, the car starts up and runs fine cold, drives completely fine. It even idles pretty good now...right up until it doesn't. The symptoms now include a horrible miss and most often stalling at idle, but it only happens once the car is good and hot. Idle adjustment screws aren't making a difference at all. I mean, they can make the car idle better or worse, but they're not fixing the miss. The only way I can keep the car running is to pop it into neutral at stop signs....seems like keeping the idle up alleviates the miss.
Here are the car vitals:
Vacuum:19-20
Base timing:12 deg advanced
Idle rpm:around 1000, drops when in gear to about 800
Valve lash:12/22
I'm back to it being either a carb or spark issue. Would a failing fuel pump do this? It runs absolutely fine off idle.
