Thanks all! Im hoping its the starter because all the grounds and cables are fine. Dont know what a carb spacer is...
Apparently, neither do your "mechanics". Especially if they are not familiar with our old cars with carbs. A carb spacer fit's between your carb and the intake manifold. Ideally, you chose one made out of a material that limit's the transfer of heat. Heat from the engine is transmitted to the intake and onto the carb. Two conditions occur when an engine is shut down after a prolonged drive...
1.There is a condition called "heat soak". This is where the engine temps increase to a certain point beyond those temps when the engine was running before you stopped. Perhaps, 15-25º plus degrees. This increase can cause fuel to "boil" or vaporize in the lines and in the carb fuel bowl. This sets up the second condition ......
2. "Vapor lock" this is the result of that "super heat" finding's way to the carb bowl and fuel entry lines. The fuel will vaporize, therefore, when fuel is called for, liquid is not dispensed or available , instead you have "vapors".
Starters are prone to be affected by this "super heat" as the windings may expand if the heat is too extreme, and the armature will rub the field windings and other nasty stuff.
So, how do you minimize this stuff?
1. Insure your cooling system is "spot-on" (numerous little tips available)
2. Add a phenolic carb separator, perhaps, a 1/4 to 1/2". Be mindful of your hood clearance.
3., Timing to far advance can add to the previous 2.
Perhaps, others will offer other tips......Good Luck
