This car has sat in a garage for a couple of years. I have it running well once it starts. Changed filters, new gas etc. It is very difficult to start when it is hot after running awhile. It starts after cooling off. I remember this from the 1960's, but not what caused it. It has a single barrel Fomoco carburetor. I suspect some of those little levers and adjusting screws are seized. I don't know the carburetor that well and I haven't obtained a manual yet. Any suggestions?
