deputydog,
If you think I need a glow driver why didn't you vote that way? Even inverted you cannot lean much more than the upright setting. In fact most 2 stroke engines you can get the tuning setting perfect upright and they run fine inverted. I am finding that running a bit leaner does nothing except make transition worse. The engine is not actually totally inverted but at 45 degrees down tilted to the right with the exhaust valve down. Although the plug was getting a lot of oil in it, that no longer seems to be the case. I think its the added viscous drag of the oil in the crankcase. It completly fills the gap between the piston and cylinder and drags. Unless you cut the engine after it is running at full throttle it is stiffer even when the valves are open. Kinda like when a tight engine is first broken in, it needs glow power no matter what the mixture is.

So far I think PatinIdaho has the correct answer, though a glow driver would certainly work. But, I would rather not have the extra weight, and something else to charge up.

BTW What glow driver do you recommend?
