Re: Overheating issues

Two negatives!
Eddy carbs don’t like more than 5 psi. With your pump you might be flooding just enough when it gets hot to cause your idle problems.
Also at 850 rpm you’re likely already kicking in the mechanical timing in the distributor. That means your 11 initial might be actually 3 or 4 or less degrees. You need to get the idle down under 750 rpm, then set your initial to 14. Lack of timing is a heat builder.
