The kit didn't include the o ring, go figure. I had to order them separately
, but that's what I have on now, which replaced the old style flat washer.

s looked for issues. Found one of the four screws that holds down the rubber
diaphragm loose, very strange because I have never removed this before. Any
way figured this was my problem. Fixed took off all ok. Got home. Next day t
ried full boost, same issue again, didn=99t take off. Got carburetor r
epair kit and went through both carbs. Reinstalled carbs double checked. Sta
rted right up, as I move the throttle past 2300 rpm the yellow caution light
starts blinking, engine runs rough, reduce rpm the light goes off, increase
the light comes back on. Seems the engine runs off the idle jet ok but not o
n the main jet.

e looked at the vent lines. The yellow blinking light can indicate a sensor f
ailure, seems like it would continue blinking if there was a failure. Seems o
dd that it stops at low rpm. Seems I have some kind of a vacuum or pressure i
ssue, but am running out of ideas. I am about to go and recheck again! Could
a faulty sensor cause this?

Worse yet, we have beautiful spring flying weather!
