I would run this engine some on a test stand first to get the needles set. (do it just like you did your two cycles.) Run the first tank slobbery rich wide open throttle but richen down around 7000. Alway keep the mixture rich enough to where there is a smoke trail behind the engine.

The glow plug may work in your engine and it may not. The best plug is the OS 'F' for that engine. If you cannot find one, you might get by with a Enya #3. Break it in on 10% but after you get it broke in you want to run 20-30%. 13-6 is about the smallest prop. A 13-7 or 8 would be better.

Keep in mind that this engine has a very strong torque kick and may shake your airplane so much that you think the prop is out of balance.

Also on a four cycle if you get it the least bit lean, it will back fire and bust the spinner or throw the prop off.
