Runs/Idles rough and what I've done so far

[HotRodHell]

My new '31 is running rough at idle and will have a vibration in the steering wheel and body in general. It also seems to need to idle a little on the high side to stay running and not lope. While driving it will die when I come to a stop at times and also backfire on deceleration. It does seem to have adequate power. Before I got it, it saw less than a 1000 miles in the past 10 years and I believe absolutely nothing had been done to it either.

What's been done so far. Cleaned and gapped the plugs, set points, adjusted the distance of the rotor to distributor contacts, set timing, cleaned fuel filter and screen in carburetor. The timing was dead on, but all other gaps were off. It seems to have a strong spark. The cap and rotor seem old. Should I replace any of the ignition components? I also have replaced most of the fluids.


I think the carb should be rebuilt. Am I missing anything? Do you think the problem is in the carb?

I would just like to get it running well. Any suggestions will be appreciated!
