I started my day pulling the aircraft out of the hangar and running a couple more High speed taxi runs to check for new clues to the engine stuttering issue. I found that running either pump made no difference, however if the engine was at full throttle for a few seconds then brought back to idle then quickly throttled up again, the stutter would almost go away. Kinda like back in the RC airplane days, when the carb wasn't tuned right, if it idled too long it would get too rich at idle and stumble at throttle up. Weird. gonna have to report this to UL and see what they have to say.
I then pulled the ez back into the hangar and began Inspection prep by safety wiring the prop bolts. Tomorrow is the big day!
BTW: The cooling plenums are working fantastically well.
