Good eve, I wonder if I could ask a couple of ?'s. A couple things jumped out at me as I was reading through all of the replys. I noticed that not once did anyone talk about a "thrust washer" to prevent the prop from "pulling" the crank out of the front of the crankcase. Is this not a possibility? I am completely green to this but that is what I heard years back. Secondly, how is the prop fastened to the crankshaft? Is it a good thing if an engine has electronic ignition? I had a stihl 70 cc chainsaw that I would like to try something with given to me. lastly, and thank you for bearing with all my questions, how would a person know what size a plane to put a given engine onto?
Thanks for your time. I look foreward to learning from all of you!!
