Best I can tell you is think of the tripower as a four barrel with remote secondaries. In other words, block off the outer two and attempt to calibrate the center for idle and high vacuum. Then attempt to calibrate the outer two for WOT.
An exhaust gas analyzer would be a wonderful help in calibration.
And still the best advice I can give is replace it with a dual quad.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |
