Thanks for all the ideas, guys. J-, Thanks for the pics. I actually knew what the Thermac and shoke tube were. I had been there before. Mine is as yours is. The tubes and hoses are the same and the tube to the valve cover is the same.
A couple questions and a few reiterations in responce to everyone's comments:
The carb. has not been rebuilt. I believe I stated that previously? BUT....if it was a carburator problem wouldn't it also show up while driving?
Every once in a while, I get on it just to hear her roar. Never a cough or sputter. She goes like she's just been waiting for me to give her more fuel.
I don't smell gas like I would expect if there was a flooding or a leak situation.
I think a gasket leaking air into the carb. is a possibility because the car sat for years without being driven and I know gaskets dry out. This may also explain why temperature seems to affect the symptoms? Deminsions change from hot to cold and visa versa.
The fuel pump, fuel line and filter are all new this past summer.
Based on my drive, Thursday, and the change in outside temperature I think we may have to wait until it warms up again to get the symptoms back. I will go for a drive again this week end and see how things act. Thursday, I could not recreate the symptoms, but it was 35 degrees outside and this past summer it was a lot hotter when this happened.
We'll see................
The Service Manual says its a fuel pump problem or a stuck float needle. However, the trroubleshooting chart in the Service Manual does not specifically deal with "Hot Starts". It referes to failure to Hot Start as a "starting proceedure problem" and if that is not the cause then look to Cold Starting problems for a solution. Not really very definitive.
One thing I want to try when this happens again is to take off the air cleaner cover.
I did that once last summer to watch the choke and it may have actually helped the situation. I didn't have to crank very much with that cover off. The choke, by the way, slowly closed as the engine cooled down, as it should.
