I got my question answered from http://www.cncengines.com/ where I bought the Hall Effect tester and timing setup. He recommends 28 BTDC. This is set just as the tester buzzer and light goes OFF.

After 2 gallons of Lawn Boy the rpm at full throttle seemed off. Checking the carb I saw that the carb insulator does not give a smooth transition to the engine. I am working on that and will post results with a 19x10 prop later. Can't use a 20x10 right now since I am breaking in the engine on a Giant Scale Big Stick.

No problems with the Melody ignition so far. BTW using an Ignition Battery Eliminator Circuit. So far no interference with the FASST receiver.
