Rather than using a third channel remote switch and servo(but still using a remote mixture valve),Has anyone thunk up an idea using a bellcrank type system that would allow leaning of the carb mix when at 3/4--WOT,whereas it would toggle back to it's origional mixture at 3/4 and below....I think this set-up would be more beneficial than using a servo,(you could never over-lean the mix) and max performance is there when you transition between 3/4-WOT,to cool the engine down,just run at 3/4 throttle fer a bit....but for the life of me in my sober mind [:-],I can't picture the set-up..[&:]....help please... oh, this is what i'm working with...thanks cmb.21 w/3rd ch. carb mounted needle plate...Thanks to James(TopFuel4430) Clegg at Ovalexpressracing.com
