I found the screw! Now it still won't start! It tries and tries but it just wont start! I have tried everything but get inside the motor... I am tempted to do that though! I am frustrated with it! Anything else I can try... could the intake get clogged up?

 

One more big problem, I now have no power. Well, I have power to the brake light but when I turn the key and try to start it nothing. Is this a bad thing? Is it the starter?

 

I've been beating my head against the wall for weeks with my sons artic cat 90 2x4 2 stroke . It has spark , it's getting fuel . It runs . At times it bogs out as if it ran out of gas . Cleaned carb / changed spark plug . Ordered new ignition coil . The are two outputs from the gas tank . 1 to the carb , 1 capped with a screw. . The petcock is missing . There is a fuel filter coming from the motor but where does the other end connect to ? Any suggestions . I'm thinking a short in the ignition system , that line from the motor to nowhere or something else electrical. New battery on order as well . Any suggestions would be helpful. ...
