I heard it. You have something fu**ed up. Electric pump?
You really need to open up that carb.

I tried it with both the electric and the mechanical, fuel pressure gauge reads 7-8 cranking with the mechanical, drops to 5-6 as it’s reving. Electric is pushing a steady 10 psi cranking and “running” , it has a built in regulator so I can turn that down if too much

Brand new carb?

Could timing cause it to rev up like that? Trying to think if I had the vacuum advance hooked up
Edelbrock carb? No more than 5# at idle. Holleys only about 7#. I bet the pump is causing the carb to bleed over.
Unhook it and plug the hose with a screw or golf tee for now.

Just doing what I do
LOL! You guys crack me up!
It took him 4 months to get it to fire and you are all running to the ball trying to help like he is suddenly capable of figuring out what the next problem is and just needs a little advice.

Holley street dominator,
but if the electric pump was over pumping the carb, wouldn’t the mechanical that’s running at 5 psi fix that issue?
Oh, brand new carb. What is it? Eddie? You have the secondaries caught open. Cycle throttle wide open and back to closed. Or open the rear vacuum butterfly and see if they are closed.

Brand new Holley I got off of Mopar Tim for a fair prices. 550-570 cfm, if I recall right. Vacuum secondaries.

And now for something completely different. Wife has mad pottery skills. Her own kiln, wheel etc. when I drink mead I love to put it in one of her clay goblets. Makes me feel all kingly! Mead is from local guy. Right tasty!

I’m still thinking it’s electrical or timing in nature. I did run it a couple times with no fuel lines going to it, just full bowls, until it died and it rev’d up the same way. It’s why I’m skeptical of it being carb related. Both butterflies are opening and closing normally. Even disconnected the throttle cable and kickdown to manually move it and it didn’t change
Nice!!
VACUUM!!!!!

Ahh, my bad, no I didn’t have a vacuum gauge handy, I’ll be hooking one up tomorrow. I also have an A/F gauge I’m gonna put in tomorrow too.
Jeezzz. If the engine is running fast, with the throttle closed, then it has to be getting Air from somewhere!!! A vacuum leak. A BIG leak...run away till it leans out and dies...

Not disagreeing but where? I have all the vacuum ports plugged with new vacuum caps.
I did try to spray ether around the carb but it’s difficult to do it and be in the car lol
