Grumpy do have a write up also of what all the different adjustments that you can do to tune this carby. I assume the main screw is the air fuel adjustment but what should it be set to firstly? And the same for the throttle cable, should you set the kill first to operate(important) then everything after that. I take it that you can adjust the cable length or even at the handle to calibrate stop to full speed as well? I just want to get a idea of what it should be instead of what it was!!
