That's what I've been doing, Ken: Backing off a couple clicks to try getting as much smoke as I can. As for the prop, I may switch to a 12-7 or 12-8. I have the 12-6 because I'm trying to go for torque. Perhaps the higher pitch will do the same? I doubt the Tango has enough ground clearance for a 13, and I'm thinking that the added torque may cause it to cork-screw when ever I open up the throttle. Any opinions?
