ken how are you starting it now that its colder. mine likes full rich cracked 1/4 fuel on key at the same time with revflow great planes intake. if you wash the plugs its going to act like its rich due to the fouled plugs till they clear up. my intake is new but it was the same for the home-brew manifold i have no carb heat but it has heat box with scat hose to the ex's stove. i have to be real easy at applying the ram air on climb out or it seams like its lean due to the over boast that you guys have talk about. new numbers idle 975 1000rpms static 3,550 rpm 52x 44 sterba prop .you just might be flooding it use Jim faughn method of tuning and you will probably will be OK it just sounds out of adjustment
