Re: IML: Part Time Rough & Powerless '56

I'd be interested in knowing how the engine runs after slowing down from highway speeds. Does it catch up with itself and then allow another highway speed run for a while before starting to stumble and miss?

If so, I would think about fuel starvation as a possibility. With a lowering float level things start to run lean enough to cause your symptoms.

By the way, if distributor shaft wobble were the problem, I think it would show up more at idle. The fact that it runs reasonably well for a while at high speed removes most of my concern about the distributor shaft bearings.

If the distributor has slop, it certainly should be rebuilt. That said, I am thinking that this car was running pretty well not long ago. You mentioned replacing ignition points. Are you positive that you gapped them correctly? They can be tricky in that both sets aren't always on a cam ridge for gapping at the same time. It is often necessary to "tick" the motor separately for each set to get them adjusted correctly. Also, the gap should never be anything outsiode of .015 to .018. Also, plugs should be gapped at .035.

I hope I got my decimals right lately my math has been terrible. You can verify these numbers in the tune up specs.

As those who have been following my posts over the last month or so know, I've been battling problems in rebuilding the carb on my '56. About three weeks ago I decided that there were too many wire gauges that I don't have that the chances of my getting all the adjustments correct on my Carter WCBF was nill so I took it in to a local shop that still does carb rebuilding. It did take them two tries to get things working but last Thursday I mounted the rebuilt unit on the engine and it started right up and idled very well.

Driving performance is definitely better than before any carb work was done but once hot, the engine still sputters and skips under load and will only maintain highway speeds for a few minutes before losing power and skipping. This is the type of performance I'd usually associate with a modern car with a plugged cat so I'm somewhat at a loss for what may be the problem. I'm guessing distributor but would love thought s or suggestions. As background, the plugs, wires, coil, cap, rotor, and points are new as of last summer however I have not yet pulled any plugs or checked the cap and rotor for signs of trouble. My recollection of installing all those ignition parts is that the distributor itself was loose and therefore probably on the verge of needing to be rebuilt/replaced itself. With that in mind, any suggestions for good distributor re-builders?

Thanks,
