What's the fuel pressure supposed to be?

Exactly what is it? No guessing. what does the fuel pressure actually say?

Just for giggles dump 2 teaspoons of gas down the carb and attempt to start----What does it do exactly? Does it try?

Voltage? Key On, what is the positive coil voltage?

While actually cranking what is the voltage at positive coil

What I'm getting at is, Is "I" terminal on the solenoid providing that needed "BOOST" to the coil while cranking?

What's the answers to my questions?

ctorj - I was told to try just tapping the pedal before starting but that doesn't seem to help. I haven't tried giving it a good shot with half pedal but I will try it next time. But it doesn't seem to be a "summer time" only issue. It started in late winter.
Don't stab the pedal. You slowly go down to try not to squirt the accelerator pump. Try not to add more fuel to the engine when you restart it on a hot shut down.

If you slowly push the throttle to 50% and it starts up way faster then I am right of the fuel boiling out and through the venturis.
If you find a fix let us know. My poor 25 year old starter is having the time of its life.
Cut a hole in the bonnet above the carb, put a scoop one the top of the carb so that it sticks out through the bonnet, and Bob's your uncle.

Eh, voila

If the hole in the bonnet route isn't your cup of tea..

Detach your bonnet at one hinge.
Run stud nuts onto the hinge studs.
Run short studs into the stud nuts.
Fasten your bonnet up again.

Repeat at the other side.

The trick lowers engine room temps at slow and no speeds.

I've never tried it with a GC, so it may be a little more complicated than my simple instructions.
