i would like to know what the air/fuel screw would set on.thanks for any help

 

In your case with the cv carb its called the "fuel/air" screw since the adjuster is closer to the front of the carb than say the 400,300,250 2-stroke carbs with the adjuster being closer to the rear of the carb and have "air/fuel"adjusters! Not trying to be a smart a**,but adjustment is more sensitive on your carb than the others! Plus if still has plug over adjuster, must carefully drill small hole,use a screw to pop out plug.Base setting should be between 2 to 3 turns outs. How I adjust one,especially if have one that has performance exhausts,etc,is to start at 2 turns at idle and turn out until starts to drop rpms,counting turns,and then in until rpm change,Then set midway between both points. BUT if just rebuilding,etc 2 1/2 turns out from lightly seated (closed) position should be ok. If boggy on accelerating,then try a little more out. Maybe I'm getting a little too technical,but depends on your situation. Plus this adjuster on either type carb affects basically just idle and slow jet response. Good luck

 

thanks for the help.i just put the 2 backwards when i typed.never to technical for me i work on a lot of atvs .
