‘40 V8 stumbling when accelerating in 1st and 2nd

[mike42]

Good afternoon ………

I’ve not been on for awhile due all the damn work I’ve got here in northern Michigan. With that said……I’ve asked this question before, but still have a problem. I continue to have a stumbling problem when accelerating in first and second gear after driving for 10 to 15 miles. When cold it absolutely runs and idles perfect ! I’ve changed coils from Skip Haney……new IH200 condenser and had a new carb from Dennis Carpenter. The new carb ran great for about 5 months and it started to stumble.

When cruising at 50-55 mph it’s runs great !!

I even had Charlie NY rebuild the original ‘40 Carb, but that was very hard to start cold or hot. He’s been good enough to go through it again.

With all the talent here……..is there anything else someone can think of that I should be checking out ?

Thanks very much.

Mike
