In all the years I've been around here, I can honestly say that itey is stupid knowledgeable about carbs and timing curves. The guy knows his shit.

When he speaks, I listen.

Carbs are a form of art, not everyone is good with art..

I spent many of hours/days/years, playing with carbs. And I still don't know shit..

Knowledgeable and unreasonable.

How dare he ask me to make my car quiet so I can tune it listening for knock

Yes, he helped me on YB, or tried to, lol.
I feel the same and had a lean carb lift a ring land which is why I had whitener make a new carb for my xe engine.

Some of tuning seems like science, and some of it needs like a witch doctor is needed.

It's fun to sit back and watch this shit.

Hopefully soon he realizes he's not the only the fucker in the world to have struggled with a timing light/vac gauge/and a flathead screwdriver...
 
Honestly wish I could help more. Only so much a fucker can do from way over yonder.

P.S. I think 24 degrees initial is way too much. Don't care what cam is in that little ford engine.

It's the whole reason I have a distributor without a vacuum advance port, locked out, and had a carb made 😆🤣

Sounds like 24° initial with vacuum advance connected will pull in timing while cranking, vs being locked.

I'm likely to end up going ported vacuum instead. We'll see how it plays out but my gut says 20-22 base with 10 or 14 limiter bushing on ported vac should make it drive better

Bleeds and restrictors may need some adjusting
 
This is what AI says though it may be hogwash

Because your idle mixture screws are only 1 turn out, you have artificially restricted the fuel in an attempt to clean up a rich condition caused by heavy mechanical pull on the idle circuit. This leaves the transition slot competely dry when you open the throttle resulting in your lean stumble.

Because the current 33 ifr and 75 iab setupis relatively rich for the idle circuit your throttle blades are likely closed too far to manage the rich idle mixture. This forces you to lean it out using the mixture screws which starves the transition slot for fuel.

Your .033 IFR is massive for an engine with 9" vacuum at idle. Coupled with your highly sensitive annular boosters the carburetor is dumping too much fuel into the circuit. The .075" IAB is relatively large. While large air bleeds generally leans out the circuit, in your setup it is delaying the signal to the transition slot. Because you have the mixture screws cranked down to 1 turn out to fight the .033 IFR, there is not enough fuel volume waiting in the transition circuit when you tip the throttle
 
It actually said to go smaller on restrictors and leave air bleeds, but it's easier for me to drill the idle air bleeds to 2mm and see what it does
 
Also, I found that 600hp in a light car I was barely touching the throttle to do the speed limit, probably still in the idle circuit.
That how you feel ?

I don't expect you to understand this, and it's very possible you don't even care. But to a mechanic, there is probably nothing more offensive than saying.. "google/or AI told me"....

The funnest car I ever had the privilege to drive, was by faaaarrrr a Mazda miata with a 5 liter small block ford with a solid rear diff.. piece of shit probably only made 300 horse, but with the fun stick it felt like 1000!

Doctors, veterinarians, mechanics... the growing list of people that hate AI.

Fact is AI can be much more thorough and break it down so simply even Ricky Retardo can understand.

Whether or not the answer is correct is why it can require confirmation

"Skip AI and stick to a car forum for your facts" LOL

I'n with you, I also think AI sucks but when it cuts thru all the bullshit to get you close to your answer it can be nice.

Even more fucked, ya might as well use ai because when you go to the mechanic/ vet/ Dr, they're using it to help diagnose too
