Got a better meter today.. and it turns out my cheap meter wasn't too far off after all.

So I still can't dial in the numbers specified in the procedure. Using the yellow/blue wire pair, it says I should shoot for 4.42K with the throttle closed. The LOWEST I could get it was 5.17K with the sensor turned fully CCW. All the way CW ramped it up to 5.72K.

So then I tried using the yellow/black pair, and did manage to get it set for 0.81K (as the procedure indicates) with the throttle closed... but when you open up the throttle, it runs up to 4.8K, well past the 3.96K it says I should be looking for.

Any thoughts? I'm inclined to leave it as it is and see how it runs. I'm doing the testing with the carbs on the bench, so WOT may not be as much as I'm giving it by hand, so the open throttle number may be a bit overstated. Not sure by how much though. Grrr....
