I was wondering if either Dave or any of you other YS gurus could shed some light on a problem I am experiencing. My 63FZ is having a problem with quitting at high throttle. I weird thing is it does not happen with the glow ignitor attached. With the glow ignitor attached the engine runs perfect. Upon removing the glow ignitor at idle there is a noticable loss in rpm. When the engine starts to choke down at 3/4 to full throttle all I have to do is reattach the ignitor and the engine clears up. This sounds like the glow plug is not good but it is a brand new OS F. The engine is mounted inverted in an flip3d. I run it on powermaster 20/20 with an 13x4W APC prop.

I was also wondering if a conversion kit is going to be available to move the regulator to the new position on the YS 63S. This would help us who have problems with the engine on the hot, humid days like here is on the Gulf Coast. This would be an nice option to be made available.

Thanks
