Mine is a 2 blade 70x76 BW wood. I had to replace the carb last weekend and I have a suspicion that the linkage wasn't set up properly to get full throttle. I bought the plane...didn't build it. Original owner couldn't remember anything but having to put smaller jets in to fix a rich issue.... which would align with my current thinking. Even so, it would run 2750 wot at 3000'. Now that I have the linkage correct, I'm thinking it wont have enough prop at now true full throttle.
Also, I can't figure out how to get full travel on the mixture arm. My quadrant gives 1-1/2" of travel, but the mixture arm on the carb needs about 2-1/8". It was an easy fix on the throttle...just drilled another hole higher up on the arm. As you know, the mixture arm is curved and bent.
Any thoughts?
