I use an electric start as this is an older mag engine that is hard if not impossible to hand start. Since prop position for starting is not critical, I would like to place it for best engine balance. I think I remember that the prop lines up with the rod @ TDC, but I am not sure.
I get what you are saying here....and I know this has been hashed out on here somewhere at least a time or two, but for right now the threads are escaping my search. I recall in the end that the position ends up having little affect in an attempt to balance out a single cyl engine. There was talk about having a slightly out of balance prop, positioned in an attempt to counteract the inherent imbalance a syngle cyl engine promotes....again in the end it appeared fruitless.
I would make every effort to get your engine properly tuned, cooled, and balance those props/spinners...and fly.
