I can rule out firing order because it revs up an runs beautiful with choke almost closed. if I remember right when I had the vacuum gauge on it, it read 16. Timing is set to the notch on crank pulley with vacuum line disconnected What are some common spots for vacuum leaks on flatheads?

After 4 hours at the shop, here is what I came up with. Just to recap, trying to get an 8Ba flatty to run right using 2 different model 8BA carbs 1st carb, I cleaned myself and put a kit in, idles smooth but backfires and stalls upon acceleration unless you set the choke 3/4 - 7/8 closed, then...

When I look in the carb, fuel comes it of the nozzles when you step on it, but it comes out in a solid stream. Should it not be more of a mist?

I'm not at the shop at the moment, but when I get there I will check the nozzles. And yes I did remove check ball from the bottom of the accelerator pump well, cleaned that all up, replaced it, and did the check to see if it was seating properly

For now I'm going to concentrate on the one that I put together, and the problem with this carb is, idles beautifully, but you have to have the choke 7/8 closed to accelerate, otherwise it stumbles and dies. Alan said in a previous post that I should study the three circuits and then go at it...

All I know is I need to get this problem sorted so I can run this thing proper and seat the rings

I can't say anything for the rebuilt carb I just bought(the second one) but I know the power valve is correct in the carburator that i put together is correct and does not leak. We have two different carbs here, an two totally different problems. Hard to blame the same thing on both carbs, but...

I'm about to pull my hair out. and I don't have much left, so I hope I can solve this problem soon. This is going to be a long message, but I want to give as much info as possible. I rebuilt an 8BA to factory specs, ant put it in my 51 Mercury pick-up. The first carb I overhauled for it is a...
