This has me a bit nervous and I am wondering what to expect. What is the standard procedure for hand starting a gasser? I have a lot of experience with 2 stroke engines and have hand propped full scale planes but that 20 inch prop has me a bit intimidated. All suggestions appreciated as I don't want to get hurt!
So far, no one has mentioned the differences in ignitions. Most newer ignitions will retard the spark during a brisk flip of the prop and this will allow a fairly easy and safe hand start. But there are still ignitions out there that don't retard (are fixed timing) and will bite you if given a chance. What ignition are you using on that older Tartan and does it retard during startup?
