I tried the throttle connection suggested by RAM3500-RCU and it worked OK. I can't quite get full throttle that way but it is adequate for the GP Super Stearman. I ran the engine on the ground for the first time today. It started easily, idled well and ran great. It does seem to have more vibration than my previous engine and yes, the prop has been balanced. I should get a chance to go fly it for the first time in the near future.

Best wishes and good safe flying.
