I did clean the air bleeds, along with bumping up timing a touch.

1 mixture screw was out 1 and 1/2 turns, other 1 and 1/8 from seat, per using vacuume gauge. Both now at 1 1/8 just for testing.

Car ran much better, 40 mile trip. Hardly any stumble, if any at all. So I'm really unsure just which adjustment helped the stumbling issue. But thanks for the idea anyway.

I've always tried mixing at least 1 (avgas, racing), to 5 gal 93 in the car. And maybe even wonder if timing wasn't my biggest problem. But don't understand why the stumbling would have started for no reason other than the air bleeds.

Car seems to be back to it's old self now,,

Thanks again.
