Thanks Bud and John.
Apologies for not replying earlier. Thanksgiving morning I flew to a grass field
nearby and when I went ahead to takeoff found that the engine was only
developing
4000 RPM (relatively smoothly). Aborted takeoff and two days of troubleshooting
later discovered that the diaphragm on the port carb was shot. Luckily
found someone with a spare and was able to get back home safely yesterday. It
was not easy to find the culprit and had some Rotax savvy friends baffled. A
check with analog carb balance gages finally pointed to the root cause.
Its true that my engine sat in its crate after overhaul for three years and
flown
since March but never imagined it would need another carb overhaul so soon.
Go figure as I was told this is rare. Crappy parts?
Anyway, drama resolved and thanks for the filter info. I will look into it
today.
Best,
Chris
