So, without reading the ton and a half since I posted on page 2 or so, what is the verdict?

Has there been a cause found? It looks like folks are still throwing out ideas.

What is the actual cause, and if not known by now, why not? Can't believe 11 pages and no cure.

1) An engine needs three things to run: compression-spark-fuel.

2) A repair cannot be made without first knowing how the part or parts in question work.

3) I think that everything that could repair the problem has been covered at least once here.

maybe i've just missed it but have you changed to carb? I've seen the question asked more than once but never a reply.
A story related to me about a simular problem was the result of a couple of pin holes in the float that would cause it to fill slowly and then drain after the engine was shut down.

Sorry for the brief delay. Something "more important" than my Model A problem came up. I know, how can that be, you ask?

Back to take a long test drive tomorrow. I haven't forgotten my promise to keep you all posted.

FOLLOW-UP/UPDATE:

Mid-range drive showed no recurrence of this problem but will need to go farther to be sure.

Also, before the latest test drive a "tractor-like" chugging sound along with some louder air sucking noises developed from the engine which appeared to be a blown manifold gasket. We removed the manifold and found that the fiber-style gasket (installed not that long ago when the engine was changed) was in pretty bad shape. We guessed this was used instead of the better metal gasket because the cheaper type come in the kit? Anyway, metal gasket has now solved these problems which we noticed AFTER the primary trouble, so it's not likely THAT was the cause of the sputtering/won't-go problem.

Won't be able to update again for a few days but will not forget my promises to keep you posted so hopefully all will know what WAS the problem, those of you with similar troubles can try THAT fix...and somebody will get the prize they deserve.

Your existing manifold to engine fit & your manifold gasket leak could possibly be "the" problem(s) for at least (2) of the engine's cylinders fed by your intake manifold.

1. Remember, everything is great except at caution lights when the engine heats up.

2. The manifold can heat up & expand; & the manifold gasket can move slightly & start leaking increased "air" at the engine's intake port feeding (2) cylinders.

3. Increased "air" can cause an insufficient supply of fuel/air mixture & also too much "air" in the fuel/air mixture.

4. Remember, pulling out the choke helps the missing engine run a little better -- possibly because this adds more "fuel" to the intake's "air" leak.

5. Appears wise to check "flatness" of the combined intake/exhaust manifold surface & install with a more permanent copper manifold gasket, especially near the coast in areas of high humidity.

Not being able to "see" what you have, just one more "guess" to consider.

Also remember to re-tighten the manifolds nuts after a few heat cycles just like head nuts.

"If" an intake manifold leak was "the" problem, the test specified in message #13 would have indicated some plugs were "dry".

Again lack of fuel where it really counts, i.e. at the end of the line where one needs both "spark" & "fuel", "inside" the combustion chamber.

Engine overheating at slower rpms at traffic lights could warrant a slipping fan belt or radiator cleaning attention.

Did you check for "flatness" of the manifold? I understand that sometimes you need to mill down the manifold to assure it is not warped or not flat. Just a comment I have read so I am no expert on this subject.

Having experienced the same symptoms I would have bet it was a clogged gas cap vent, that's what it turned out to be in my case, BUT, I know a guy who had a similar problem and it turned out to be a mouse nest in his muffler, it would run until the muffler developed enough back pressure to kill the engine and after it sat a while it would start right up again and repeat the process , go figure.

There is a lot of integrity in Mr. sgwilson904's first message; & if one studies the first remark in his first message, one already sees the sincere humility in his plea for assistance; i.e.:

"I'm new, inexperienced and at my wits end trying to resolve an issue that's about ready to make me walk away from my Model A, a '29 pickup."

Many have taken valuable time to share some of their past, unique Model A experiences in trying to help him, whereby he gave most sincere follow-ups of details.

In my humble opinion:

1. Anything invented & successfully produced by the brains of humans can be successfully repaired by the brains of humans.

2. With Mr. sgwilson904's continued progress reports, & all of the "continuing" compassionate responses to his reports presented above, Mr. sgwilson904 will definitely find the "problem(s)" in the not too distant future.

Let's all continue to be courageous -- Friday, February 6, 2013 is a new day!

Seems to me that he found his problem a couple pages ago.

Thanks Mitch -- that's a long Friday you noticed -- lasting 36 hours -- next time I'll find my reading glasses prior to typing a message.
