I run a Rotax 912s in a model 7 and it has developed a noise in the radio every time I transmit. It would best be described as a crackling popping noise in the headset. It is connected some way with the engine sense it varies with the RPM of the engine and quits altogether when I shut the engine down. I was up flying the other day and after I landed I called the FBO and asked for a radio check and he said I was a little static'y but I was readable. Could I have a bad spark plug or plug wire? The engine seems to be running fine. Do I have a bad ground some where...opinions?

The engine has never been started and appears today as it would have come from the factory in 1994. The question is do I run it as is or tear it down for inspection? The exterior and what I can see of the interior, intake and exhaust ports, appear clean and free of rust. The entire kit was stored indoors, but not necessarily in a controlled temperature environment. Also I plan to install the static ports just forward of the horizontal stabilizer on both sides of the fuselage. Does anyone have the exact location measurements for this location? Appreciate any guidance from the group.

Might be just fine in side=2C but no way to know for sure without haveing a looksee. New seals installed then also. Rotax recomends that seals be replaced every 5 years. 1994 till now is 16 years.

You can look for a bad ground on the shield that covers the mag P-Leads. That certainly would cause your problem... That shield should be well grounded at the base of the engine. Finally look for a resistor plug that may have the resistor shorted. Or a plug cap that has arced inside.

I had the same-circumstances when I purchased-my unfinished Model 2. The 582 gray head was delivered i n the early 90's and never run. I did the break-in protocol in 2005 with no problems. Perhaps foolishly, I then flew it despite it's age without incid ent.- I did have to have the C-Box rebuilt at about 20 hours, however, wh en began to slip and over-rev the engine during a run-up. There should be a service bulletin about that on the Rotax site that you should check out if you have that gearbox. The engine-now has-150+ hours-and I've gained confidence in it. It will go in for teardown and inspection soon, however. - Marco Menezes N99KX Model 2 582-90 C-Box w/clutch --- On Fri, 2/5/10, Jim_and_Lucy Chuk wrote: From: Jim_and_Lucy Chuk Subject: RE: Kitfox-List: 582 QUESTION AND STATIC PORT LOCATION I would say-have the engine torn down and inspected.- Might be just fin e inside, but no way to know for sure without haveing a looksee.- -New seals installed then also.- Rotax recomends that seals be replaced every 5 years.- 1994 till now is 16 years.- Jim Chuk- Avids,- Kitfox 4- Mn - From: ltaylor02@Chartermi.net Subject: Kitfox-List: 582 QUESTION AND STATIC PORT LOCATION I purchased, Aug '09, a 1994 Kitfox IV, which came with a new 582 grey head .--The engine has never been started and appears today as it would have come from the factory in 1994.- The question is do I run it as is or tea r it down for inspection?- The exterior and what I can see of the interio r, intake and exhaust ports,-appear clean and free of rust.- The entire kit was stored indoors, but not necessarily in a controlled temperature en vironment.-- Also I plan to install the static ports just forward of th e horizontal stabilizer on both sides of the fuselage.- Does anyone have the exact location measurements for this location?-- Appreciate any gui dance from the group.- - Lane Rutan Long EZ 75% completed Kitfox IV >http://www.matronics.com/Navigator?Kitfox-List ronics.com ww.matronics.com/contribution Hotmail: Free, trusted and rich target='_new'>Get it now. =0A=0A=0A ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message kitfox-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Kitfox-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/kitfox-list Browse Digests http://www.matronics.com/digest/kitfox-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.
