Yesterday it purred. Today it pukes at partial throttle.

What all did you do to ignition. You mentioned timing Where was it and why did you change it?

I hadn't looked at dwell and timing since I bought it (Hey it ran!) Points were too wide. Set dwell and checked the timing. Factory calls for 2.5 deg, and it was sitting at 12 deg after I set the well.

Side note; It occurred to me this morning that the engine reves fine when the car is static in the garage but stumbles so bad on the road, I have a hard time getting it back to the garage.

New condensers have a high failure rate, usually go out quickly, especially after a hot/cold cycle.

It's the old condenser. Point contacts looked good- no pitting. It's a '64 stock \6, with a Holley 1920, slightly buggered manifold heat valve and half functional manifold choke spring. The engine was at operating temp before I pulled it out of the garage.

Thanks you guys. I'll blow out the main jet today and report back.
