Engines From: "AircamperN11MS" Good morning Oscar, If your engine truly is flooded (which Im sure it is) this will be a big Ah Ha moment. It has never failed me. One other point that hasn't been brought up and I will because someone else brought up the mags. An A65 if put together proper only has one impulse coupling. It should be on the left mag. You should only be starting it on the left mag. If you are experiencing the prop kicking back and sneezing (if you will, the engine, not you) I would guess that you are trying to start it with both mags on. I have however seen engines put together with no impulse couplings or with two couplings. On experimental airplanes you never know what someone may have done. A series engine should only have one impulse coupling. (it should be on the left mag). C series engines should have two couplings. O-200 engines should have two couplings. The impulse couplings will retard the timing and fire the plugs late to prevent kick back when trying to start. Some old radials never had impulse couplings. They an be a real bugger to start. You need to wear your man shoes when starting these. Oh well, enough for this mornings chat.

Engines From: "taildrags" Scott: oh, no! You're sending me back to my books to read up on Continental ignition systems! Upper plugs, lower plugs, gapping, timing... I know my mags and plugs are set up just the way they're supposed to be but I did all of that work more than a couple of nights ago so I've forgotten it all ;o) Honestly, I *always* prop start it with the mags on Both, and I believe both of my Slicks have impulse couplings. However, this is a good time to learn something (and to teach something) about magneto ignitions, so I'm going to study up and report back. Meanwhile, we've got a couple of wildland fires burning around us so I get to watch a lot of round engines fly overhead as the tankers make their circuits to and from the fires. But I doubt that I could prop-start a P&W Double Wasp on a Convair 340, with or without impulse couplings ;o) -------- Oscar Zuniga Medford, OR Air Camper NX41CC "Scout" A75 power, 72x36 Culver prop Read this topic online here: http://forums.matronics.com/viewtopic.php?p=459859#459859 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-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/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-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.
