Adjusting carb after rebuild

Just finishing up engine work on my '48 Super A that I am restoring for the second time in 20 years. In the process, I did a workover on the carb with a new carb kit. Carb (a Zenith) was in great shape to begin with, but a tune up can't hurt... right? Cranked her up and she sputters a little at both low idle and high RPMs. I have tried adjusting the main gas jet but it doesn't seem to make much difference. I can pull the choke out about 3/4 of the way and it seems to smooth out a good deal. All suggestions appreciated.

Check your fuel flow from tank to carb. Low fuel flow will cause sputtering.

As with any engine check and make sure the spark is a good blue/white and jumps a 1/4 inch gap. Spark problems can be what looks to be a carb problem.

If the adjustment does nothing as in you can turn it all the way in and not kill the engine or all the way out and not get black smoke then the main circuit is still clogged up and you when you clean a carb need to poke out all the passageways wit ha piece of wire or as I do I use a torch tip cleaner tool
