All the work to re-commission this engine was in fact done by a Rotax-certified mechanic. The starting issue is not and every- flight issue. I now I have 13 hours flying time on this plane and have only had a starting issue twice. The first time I had a starting issue, it was using the procedure that you described below, with the exception that I burped the engine first. My mechanic(rotax certified) seems to think I was flooding the carbs; however, I understand that this should not happen per your input below. Not sure what's going on yet. The rough running engine issue ( i.e. between 2200 RPM and 2800 RPM) is in fact an every- flight issue. Still working on this. Thanks for your input.

In hot or cold weather. It's not at all like the aviation engines of old. I've uploaded a video clip I happen to have when I started my Allegro. It was a cold engine and 83F weather.

Rotax now specifically states you should always have it on. To be clear, having the pump on can't force extra fuel into the carburetors (unless there is a carb issue such as a leaking needle valve, heavy or mis-adjusted floats). > 2. Throttle at idle. > 3.

If you're changing adjustments all around, something is way out of wack. I would find a Rotax mechanic to find and correct your engine issues. Not a regulator A&P or anyone else who doesn't know Rotax 912's. > You can find people at: http://www.rotaxirmt.com > It's possible, it's not carb related.

Not necessarily specific to your situation, but - not all mechanics are good mechanics. -------- N456TS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=460316#460316 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message allegro-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Allegro-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/allegro-list Browse Digests http://www.matronics.com/digest/allegro-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
