Mag .010", points if you have them .015" or adjust the point gap for 26 BTDC, plug .025". A Sullivan Megatron on 24 volts works, a friend of mine has a 40 with an Eastcraft on-board starter that really works well. B&B has a Walbro with a choke available, don't know what the number is. I don't how the engine compares to today breed of 30 cc engines, I expect it's heavier. I don't think you will wear it out however. The 35 spinned a Zinger 18"X8" at 7200, the 40 spins the same prop at 7500 rpm.
