You can get a good adjustment with a 2' piece of heater hose to your ear, listening at the base of each carb and adjusting to equalize the sound level. IME, the tools don't give much better results, because it is very hard to equalize the seals between the tool and the carb tops.

I always thought that you adjusted the stop so that the vent just opened when the arm rests against it.

I think I have one accel pump left. Pls send me an email to remind me to look for it when I get home on Friday.
