hi thanks for the reply - it is a schumacher raptor and the manual is useless - only a parts book - my mate said that is all it came with - he had the screw on the throttle lever side screwed right out and the idle air screw screwed out as well the main mixture was out about 5 turns the one on the main fuel inlet was out about 2-1/2 turns that is why i was after a base rule of thumb setting to start with - i fly electrics mainly but have had about 20 years exp. with nitro planes but they are a differant kettle of fish to these to tune

Looks like i'am on to something now - is the low end needle the one on the throttle lever end or the muffler side - i assume that is the idle mixture
thanks

The low end needle is the one on the throttle lever side. The high speed and idle both should be on the muffler side. With the high speed being the larger.
