Outer booster removal project?

(1/3) > >>

77cruiser:
Started on this last winter, had a CC carb & I just blocked the solenoid hole. Removed the outer boosters just to play with, but under load it goes real lean. It's a SMAB carb large primary. I tried reducing the MAB to .031 still gets lean under load. Thinking about blocking the bleeds & trying it.
I have a 72 jet with no rods.
Is it even going to work, or does the large primary carbs not work for this.
Was thinking about adding a POE for the primaries?

Cliff Ruggles:
What is the carburetor part number?

77cruiser:
17085226

Cliff Ruggles:
I've done a few of the later SMAB units and they were fine running straight off the jets. 

Is it only going lean on the primary side at heavy throttle?
