Gentlemen, I also have purchased the powerhead from Lawnstation. I currently have it all stripped out of chainsaw parts and ready for conversion. I also removed all the return springs on the choke and throttle lever mechanisms. This leads me to a question, there still seemed to be a small amount of spring tension on the throttle butterfly. Upon disassembly I found that there is a small spring loaded brass plunger with a o-ring that is actuated by the brass butterfly valve control rod. I am concerned about the throttle servo having to over come this spring tension while flying, putting unnecessary load on the servo. Does anyone know what this plunger does? It seems to come into play when the throttle is reduced to idle. My engine was one of the pro series if that helps. Any help is appreciated.

Thanks,

Maximus
