Holley floods engine

What you really need to do is learn a little bit about how carbs work.
Go buy a used copy of Urich and Fisher's Holley Carburetors and Manifolds, HP Books.
I'm sure you can find it for less than $10 delivered.
While waiting for that, there's always Mr Tech 1966 carburetor fundementals in the Chrysler Master Tech series on-line

Dano and Val gave you good advice.
Buying another carb isn't going to do you any good. You still won't understand them. Still will hate them. And still will be frustrated when something doesn't work right.
The picture of that carb in the link Dano posted showed bowls with sight plugs. If yours has sight plugs then that's what you have to check.
A carb, particularly a Holley, that has sat for 4 months, never mind a year, should be checked over if it had fuel in it.
I don't always listen to my own advice - just had leaking and overfilling secondary bowl on my cuda after sitting 6 months. LOL. Then I followed my advice.:rolleyes:

You are correct. I should learn more about carbs. Hell I knew a lot more 15 years ago. I quit wrenching on things back then and forgot a LOT. It is embarrassing how much I forgot about wrenching. But I'm in an entirely different profession now and in the middle of two remodels. One to live in one to rent or flip so my time is super limited.

This project is strictly to teach the boy how to work on things which is why when he lost interest we stopped. Now he is interested again and work resumes. Who needs sleep anyway. But his school and track schedule limit wrenching time as well.

So this is a long drawn out way of saying I have no idea when i will get time to educate myself on the holley. But I had forgotten I loaned my old man a shiney new edelbrock 750. So we bolted it on with the adjustable regulator reading 4psi. Let the pump fill the bowls pumped it twice and it ran. I still have a bit of a intermittent miss but I can't hear any rods hammering or valve train noise over the open headers so combined with the compression tester readings I'm going to pronounce this engine good enough and we will keep working on getting this heap driving.

Thanks to everyone for the tips. I have forgotten so much since I built my last one I'm sure I'll have more stupid questions.
