From: "darinh" My EGT probes on my 914 keep coming loose (they are safety wired so they will not come out). Does anyone know of a threadlocker or retaining compound that will withstand the temps? If not, what is everyone using to keep these darn things in place? If you know of something, a manufacturer and a part number would be greatly appreciated. -------- Darin Hawkes Series 7 (Phase 1 - Flight Testing) 914 Turbo Kaysville, Utah Read this topic online here: http://forums.matronics.com/viewtopic.php?p 9615#209615 ________________________________ Message 2 _____________________________________ Time: 04:55:18 AM PST US Subject: RotaxEngines-List: need help with 912 rotax GROUND MAGNITO's hook up From: "Geoff Heap" There are two, 6 position contact plugs at the electrical module on top of the engine. Each one has the 6th terminal empty, ready to take the grounding wire from the Magneto to the ignition start switch for shutting down the engine. I have the terminals for the wires to connect into these two empty terminals. My question is this. Do the 6 position plugs need to be removed from the electric module before inserting my wires. Or can the wires simply inserted into the holes while the plug is still connected to the module. I have inserted a terminal into the hole as a test and it will pull back out fairly easily which suggests to me that this is incorrect. i have tried to remove the plug from the module so that I can hook it up more easily but I find it impossible to remove. Ive never seen it separated so I'm not sure where the split line is. Can someone advise, Thanks......Geoff Read this topic online here: http://forums.matronics.com/viewtopic.php?p 9629#209629 ________________________________ Message 3 _____________________________________ Time: 03:04:28 PM PST US From: "Noel Loveys" Subject: RE: RotaxEngines-List: Re: Bing carb tuning The airscrews only come into play when the engine is idling... As long as you don't idle your engine for extended periods except for a five minute warm up I wouldn't worry about it... just use the factory defaults. The engine is designed to run a bit rich at the idle so extended periods of idling may cause your plugs to foul. At full throttle engine mix can be adjusted by loading the engine ( richer ) and changing the main jet in the carbs. Several people will also change the height of the jet itself with the seasons to give a bit richer mix at cruise throttle during cold months when the air is more dense. About the five minute warm up. I actually keep a stop watch in the plane for the warm up. Two minutes at a 2000 rpm idle. Two minutes at 3000rpm by this time the instruments should be stabilized and an additional minute at 3500 rpm. Once that is done I will do my mag and throttle tests. This procedure was recommended to me by a Rotax repair centre. A bonus to having the stopwatch left in the plane is I then have a watch and timer for my flight. I start the flight time when I firewall the throttle and end it when the plane has come off step (floats). I use hobbs time for engine maintenance.

Crystal, I wonder the same thing. When I first set up my 503 I read those instructions then went out and looked at the close proximity of the prop to the front carb air screw and said to myself, "Self, no way!" I tried turning the screws a slight amount with the engine off, then starting it up to check the rpms and smoothness. I ended up with the screws right back where the instructions recommended for the initial setting. I have not found that I need to change carb jets, or adjustments nor prop pitch with the seasons on this engine. My 503 is the DCDI model. It runs like a sewing machine year round. -------- Tom Jones Classic IV 503 Rotax, 72 inch Two blade Warp Ellensburg, WA Read this topic online here: http://forums.matronics.com/viewtopic.php?p 9471#209471 ------------------------------------------------------------------------------------- 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.
