How to adjust for "lean or rich" condition?
I have read a few posts regarding " too lean or too rich" .. I understand what that means but not how to adjust it. I know about the needle in the carb but not how to adjust that ... I have not taken the carb apart except for to install the throttle cable. Could someone please explain how to do this. I think my plug is on the dark side instead of the light tan it should be, what about gas mix as relates to lean or rich mixture?................. thanks
