ken I flew today over the Chesapeake bay no problems with the revflow or the crankshaft (vw ) some of you guys keep banging on the vw cranks so that was on my mind!!!! . you must be starting it wrong heres how i start mine mix fullrich fuel on crack it 1/4 hit the key or it will flood. now if it sits for a weeks it gets a airpocket or something and i just bleed it at the gas stainer and its fine. make sure your getting full lean cut off on the carb or your flooding it draning the strainer on pre flight also mine has 3/8 line. don't give up its a good carb by the way what did Joe at revmaster say the first time you had problems did you try new needle?
