Can anyone help.

I have just completed my 1st Heli, based aroung the OS 46 engine which is using a Genisis 46 muffler.

Using 5% CP fuel and a OS No. 8 plug.

I have set the needle to 2 1/2 turns and the mixture to 1 1/2 turns. (As per instructions)

I just can't get the thing to start, I have checked my glow starter and that is ok.

I am new to this game so I can't work from past experience.

Please any advice on settings?
