Low speed and high speed metering is fixed at the factory I believe.-------There is nothing you can adjust it seems.------Running issues with your motor ???

That just the nature of the beast with those models 2 cylinders..if it runs with no problems just add some Carbon guard to fuel and use it..

Something tells me this is going to be a long thread. When did the problem start? Rainbow beach, Queensland? Do you use "recreational fuel", or does Australia even use ethanol. My guess is that alcohol goes in your drinks and not in your petrol. Been to your place, beauty! I kept driving on the wrong side of the road, but everybody seemed to "like" my driving.........got plenty of "thumbs up".
