| Subject: | 912ULS running Rough |
Last Saturday I was up early to fly to breakfast with some other LSA
pilots. During my mag check, I had a larger than usual drop and
considerable roughness on the lower plugs. It still was within Rotax
tolerances, so I took off. In flight I noticed more vibration than normal
so I turned around and landed. I checked with the Matronics List Rotax
guru, Roger Lee, who suggested I regap my plugs to .023 for winter
weather and do a carb balance. I installed new plugs gapped to .023 with
no change. I then did a pneumatic carb balance at 3500 RPM. The carbs
weren't off that much according to the gauges, but it made a world of
difference. Smooooooth! And same mag drop on both circuits. I still don't
understand why the roughness appeared on only one of the mag circuits,
and not both, but I'll be doing my carb balancing twice a year now rather
than just once. Thanks, Roger!
