Thermoquad idle issue

I have had quite a few eye-burning-rich come to me. I always found it in the T-port sync......So far.
You know, I reread and edit every post I make, and I realize I harp on the sync an awful lot. I get that. But I get a lot of cars that other mechanics gave up on. It seems there is a group of mechanics in my area who have forgotten how to tune carbs.
The first thing I do when these cars come to me, is to check the sync. I never received one yet, that was reasonably close. Maybe I just get the crap jobs now, cuz I priced myself out of the market, IDK. I'm ok with that.
But I just gotta harp on the sync again. Eye-burning rich is almost always in the sync.And yes if the float-valves cannot handle the pressure, then a guy might crank up the curb-idle to compensate, Or he might crank up the timing to increase the idle speed. But the root problem,for me, has always been the T-Port sync.
And once I get that set, pinching the fuel line gets me to the right fuel level. Changing the float-setting to get the right liquid level clinches the deal.If the float valves cannot handle the pressure then a regulator would be the final answer. But I've just rarely had to go that far.
But then, I don't travel in racing circles, so the biggest tunes I get are around 250@050. And they are always streeters. That is all I accept. Streeters are a 2-gear easy pull. No big power requirement.
Altho I did work on this old crate Hemi once.....in a 71 Cuda. Beautiful car. And Hyup, you guessed, it was the T-port sync.
So Again, I know I harp a lot on that crummy T-Port sync.
But there must be a reason..........
