About all you can do is start as is out of the box, then adjust from there.

Typically, increment both primaries and secondaries the same until you have a good reason to do otherwise. If you have a mixture gage set up, you might be able to distinguish between primary (cruise) and secondar (wide open throttle) needs.

Well, now it's national runner-up and former Div 5 champ - a new division champ, also from our track, was crowned September 18th.

Tuning was more of a matter of keeping it slow enough to stay above the minimum allowed dial-in for the class. Other than that, tuning for the elevation change, since consistency is the real key and that was already established.

As for jetting, another approach would be to disable the secondaries and hone in on the primary jetting. When you've got that down, hook up the secondaries and establish the correct jetting changing only the secondaries.
