From: "Griffo" Seeing as the more knowledgeable are not responding I will give parts of your Q a go: Sounds like a no brainer but do not attempt to start with a weak battery. You will do damage to your starting system and have a poor start performance (especially cold engine and in cold weather) For a cold start If using ULP/MoGas, it must be fresh, for best starting performance adding a good slug (minimum 20 L) of fresh fuel to a slightly stale tank contents is usually sufficient to bring it up to specifications. Make sure you run your fuel boost pump until a stable pressure is achieved (turn off). All non-starting circuits must be off before cranking. I like to have my choke on full (closed) with just a mm or two of throttle. This will give a very slightly higher than your minimum idle RPM. After start - Do not be in a hurry to close your choke and then do it gradually, bringing in a bit more throttle to maintain fast idle at choke full off, engine should be at or about 2-2200 RPM. Hot start Same as above, without any choke. In fact, I like to stop/kill my engine with the RPM slightly above minimum idle, in preparation for the next start. No start! REST THE SYSTEM to allow cooling consider possible over rich/flooding may have occurred. If so, OPEN CHOKE & advance THROTTLE (1/3 1/2) ARM BOTH IGNITIONS when system cooled (be sure to have brakes fully engaged) CRANK and be ready to reduce RPM (slowly) No starter motor should be used as a prolonged cranking device so dont crank & then engage your ignition. Always arm your ignition (1 and/or 2) and then crank. As for starting on ignition 1, 2 or both I prefer both, but many pilots will start on one and then bring in the second. Soft Start (SS) First make doubly sure it is not fitted. If not fitted consider purchasing/fitting the SS fly wheel. This a fairly easy and low-cost upgrade that will give you some SS capability, without fitting the very expensive SS modules. If you have the dollars one SS Module and the fly wheel will give you all the SS you need. I understand that there was a period where the SS was fitted but not necessarily connected check for this, as I understand a small piece of wiring harness is all that is needed to bring it into effect. Cant answer your Q on the alternator on/off but my gut feeling is that it should make no difference to a starting system in good condition, powered by a good battery. Your battery, start cables & connector condition is always the lowest cost key to a reliable start. -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501060#501060 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-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/europa-list Browse Digests http://www.matronics.com/digest/europa-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.
