Tune up specs
in 912 / 914 Technical Questions
13 years ago
I recently purchased a 1996 RANS S-7 with a 912UL engine that has had the Extra Performance 95 HP piston kit installed. The plane has not been flown since 2000 and only has 150TT. I have tried to read through nearly every post on this site and would like to make sure I have some of the tune-up specs correct.
The specs I have in the paperwork all not all that specific.
Plugs called for are: NGK DCPR8E gapped to 0.22
Idle speed states 1400 RPM but everything I seem to read states I should set it closer to 1700 RPM.
I bought several Rotax oil filters and a case of the Shell Sport oil.
I removed both carbs and cleaned them, changed oil, etc. to bring this engine back to operational status. It runs great....let me rephrase...it RAN great until last night. Got some type of issue with one of the electronic modules that I will inspect to a greater depth today.
What are the thoughts on the "Soft Start" module from BullyHawk? I am new to these Rotax engines and it sure seems to stop rather abruptly. It has a two blade taper-tip Warp prop. This engine has the 4-pin electronic modules. Actually I am having an issue with one of those also and I posted a question on it in a different thread.
Anything else I should know about this engine.
Thank you,
Keith
