A good friend of mine has a Sparks 440ex with a FCR carb, not sure what size. It is cuttin out real bad anywhere below 1/2 throttle. What kind of jets do they take and what size should I start out with? He doesnt know much about quads so im pretty much the mechanic, I had to put the bigger tire on the outside last race.:rolleyes:
is the carb off a dirt bike? if it is then its a kehin, but as for what size they are your gunna have to take it a part, but before you mess around wit jetting, play around with the fuel/air mix screw a little

where is the air/fuel mixture screw at. I have never worked on one of these before so I am clueless. Thanks It was proably bought new from the factory, not 100% sure.

like directly on the bottom or on the bottom left or bottom right?
if you look onthe bottom youll see it i cant really tell you exactly where it is because its a lil differnt on every carb, but its the only screw that isnt holding somthing on, and its a flat blade
