Four stroke or two stroke? Complete model identity is needed.

We have not had two strokes here 'up over' in the US since 2002 but you folks 'down under' in Oz might have had them in 2012. We can't tell from here 'up over'.

2 stroke single carby

[boscoe99]

We here have not had a singe carby C30 Yamaha here in the US since 1997. Specification appears to be 1.5 turns out from being lightly seated. Then plus or minus 1/4th of a turn.

If you have not adjusted your idle mixture screw since the motor was new, the procedure would be to turn it inward (clockwise) until it is just lightly seated, while counting the number of turns. Write that down in your service manual for future use. When the carburetor is reassembled following dismantlement for cleaning you would lightly seat the needle and then back it out the same number of turns that you counted going inward.
