I assume you are talking about the pilot screw, the best way to set it is to start the machine and let it warm up, then slowly turn the screw inward until the motor starts to stumble, then start turning the screw back out until you reach the highest idle point, when the idle starts to go back down, you have gone too far. Set it at the point where the idle is highest and, if needed, adjust the idle to an appropriate setting.

      2007 Yamaha Grizzly 350 carb mixture screw
      By Louznmemind
      (Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
      Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..

      What's the proper diameter recoil rope to order for a Bayou 220? I didn't see anything in the manual.

      Thanks for having me.

      Hey all, Thanks for having me in the forum. I just purchased my first ATV and am stoked to understand more about it. 

      The first stupid question will be, what is everyone's maintenance schedule? DO yo follow the recommended intervals or build one yourself based on the machine. 
       
      Thanks in advance.
