Hard starts after running
Still not starting easy when warm after the 10 min sit. Ran out of time to play with it tonight. But so far so good.
That’s because all the things you have done are not solving the base symptom.
And it won’t, until you figure out how to keep the fuel from getting hot and filling the intake and any cylinders with open intake valves with fuel mist.
Gas fumes are heavier than air, and all that evaporating mist goes right down into the motor.
Then when you start cranking, more fuel from the idle circuit makes it worse.
In the end you’ll find that the simplest solution is to open the throttle till it fires up.
We can use insulators, heat blockers, return systems and non ethanol fuel, and some help.
Edelbrock type designs make that problem worse, as the fuel bowls are concentrated closer to the heat source.
Glad/hope you are enjoying learning everything you are in the process, but in the end you will remember these words, I guarantee it. :D
