Tom, I cleaned all four metering needles and jets. It had no effect on the problem. It still will not run at all below half choke.
I can't find any vacuum leaks so that doesn't seem to be the problem.
So now I am trying to find someone in my are who has even the slightest clue on how to fix this. The mechanic who I take my other cars to assures me it is a carburetor problem but he will not work on them any more. He can't make any money because it takes to much time to get it right.
I sure wish there was an expert in the Tampa/St. Petersburg area I could take it to who wouldn't charge me a fortune to not fix it.
I am now looking at all options including replacing the engine and transmission with a modern setup. Seems like a waste of a great motor to not be able to get it to run right because no one knows how to work on motors with carbs anymore.
Oh well, such is life.
