Disappointing dyno results

The 2nd set of run sheets showed a bit too lean on a full power pull, in the mid 13's at some points, then the last sheet shows extra rich in the 9's with no jetting changes....sumting wong fuel control/pressure wise...or secondary air door flaps are hanging-up. Are You sure in wiring the choke open there's no interference with any of the linkage/rods???
I agree with you. Too many inconsistencies between pulls and it all points to fuel or carb. Choke is wired open. Secondary air door flap appears to be opening but cannot be viewed during pull due to dyno parts covering top part of carb measuring air flow. Throttle manually opened at carb. Does not open fully with dyno linkage.
