Can someone give me some tips on getting my .91 sz-h adjusted? Its running really rich right now, i have two tanks through it so I think its time to lean it up. Reading the manual, it says to adjust the idle mixture, then the high speed. How do I know where is the optimal setting for the idle mixture? If the high needle is set to rich?
