Regarding Jim F's recent post to the rotax list, I had a similar incident with my 912UL. The last time I flew I had a normal run up, took off and after I got airborne the engine ran rough and would only produce 5000 rpm at full throttle. I just barely made it around the pattern and landed. I took the engine out of the airplane and took it to the Rotax dealer. So far they have put it on the test stand and of course it ran perfectly for 15 minutes at 5400 rpm. He was going to do a leak down test and other diagnostics and I have not yet heard the outcome of those tests.
On thing that was interesting though is the rotax mechanic said that the ACS ignition switch can do wacky things given the pulses of electricity that go through the switch. He suggested putting separate properly rated mag switches in the panel and using the ACS ignition switch just for starting. I had never heard of this but I will be putting in the mag switches regardless of what the outcome of the engine diagnostics are.
Jim do you have an ACS ignition switch by any chance?

Blaming the ACS switch sounds like voodoo thinking.
Switches conduct or not, sometimes intermittently, but not every other
pulse!

George:
I have a master switch, a keyed start switch and two separate "mag" switches.
