OK... some testing today. Interesting discussion above as this is the first "solenoid" conversion I can quite get right.. 1/3 to WOT is brilliant and easy to set. Idle can be set to run all day long at 2000rpm. Im really struggling with the off idle to mid range - Loading up and leaning causes a cutout. IM thinking the weird intake arrangement is causing some grief - Do you think the weird S bend and horizontal carb could cause loading in the manifold at idle? The cold aid blast on the tube probably doesn't help either.

All in all - it runs great - lots of power - 2 bladed props today - 12x6 at 9300 and 11x7 at 10000.. Easy to start and runs like a top - just have to figure the low end out.. My curve has a very pronounced Post idle dip. Might need a "special" carb.

Here is some media.
