All Small Six Help! Did I just screw up my new build?

You could eliminate the pump, get an external fuel tank. From a motorcycle, lawnmower, anything that has a hose barb, then just use gravity feed it.
Don’t get discouraged, there is progress- the videos helped a lot

Some of us just talked about that earlier. It should supply enough fuel to idle the engine.

If the crankcase has become laden with raw fuel fumes, then the PCV will be drawing that for reburning. This will cause an overrich idle. It also sounds like the ign timing needs advancing.

@63 Sprint yeah, it did clear out and adjusted to throttle position with high rpms... I guess I didn't expect it to jump up so much.
So I got carb back in November and already sent that one to Redline and got another one from them. I will contact them again, see what they can suggest. Last time they suggested to put Weber regulator (about $130), but it has the same limitation for inlet pressure.
Yes, that's the one I have 12-804. You are right, I might have too much inlet pressure. Would it be crazy to place another fuel pressure regulator after the pump before this one? Let's say just step up to the next range 4-9psi? I believe there is Holley 12-803 or something similar.

I might also put another fuel pressure gauge after the pump to see what its pushing (couple months ago I wanted to do that, but ended up skipping it).
Or as you suggested before - just install electric fuel pump, which possibly might solve all those issues...

@pmuller9 thank you, will try that as well

@sixtseventwo4d I think it started better on the first video - when I completely removed the PCV and tied it together to stop the vacuum. But I was getting smoke from the open PCV port on the valve cover - not pleasant to breathe in lol
I don't think I can adjust timing until I get it to idle on idle circuit without holding the throttle open.

@DON something like Auxiliary Gas Tank and just hang in and directly connect to the carb (or to the filter before carb)?

Let’s stay focused on the root of the problem.
The PCV is not the root of the problem.

Simple trouble shooting in the order below:
#1– Fuel supply pressure.
#2– Carburetor setup and adjustment.

We just came to the conclusion that cutting off the fuel supply leaned out the engine enough that it cleared out and started running as it should. That is where effort needs to be concentrated on at this time. Not anything else. When fuel supply is corrected or confirmed that it’s not the problem. Then one moves to step #2. Not anything else.

This is exactly what I expected.

I don’t believe that you mentioned that Redline sent you another carburetor. I wish this was mentioned earlier. Knowing this would of pointed out that the carburetor might not have been the issue in the beginning.

Yes, that's the one I have 12-804. You are right, I might have too much inlet pressure.

That is correct.

Would it be crazy to place another fuel pressure regulator after the pump before this one? Let's say just step up to the next range 4-9psi? I believe there is Holley 12-803 or something similar.

The one you have should work fine. Do not change it.

I might also put another fuel pressure gauge after the pump to see what its pushing (couple months ago I wanted to do that, but ended up skipping it).

No reason to do that. Save your money.

Or as you suggested before - just install electric fuel pump, which possibly might solve all those issues...

That is absolutely correct.
