(Ron Hoyt) ________________________________ Message 1 _____________________________________ Time: 07:27:11 PM PST US From: Ron Hoyt Subject: RotaxEngines-List: #3 cylinder miss. I am looking for ideas as to what might cause the following: On the first flight after about 1/2 hr the #3 cylinder exhaust temp went to approximately 250 degrees. All other cylinders showed the normal temp of about 1200 degrees. This occurred when the RPM was reduced to the low 4000 range and continued down into the 3000 range. During the final to the runway the engine was idled and the cold exhaust returned to normal. After landing the engine was given a MAG test and both MAGs worked normally At 3500 rpm. The plugs were pulled and all looked normal, Grayish white porcelain, dry and no soot. I believe the ignition is a wasted spark which means that I should have more than 1 cylinder show the failure if it was the ignition system. Could it be a sticky valve? Any other ideas? Thanks for any feedback Ron Hoyt N232S ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-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/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-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.
