Experts,

I just purchased a 2003 Polaris Predator 90 and could use some help. It will only start if I hold my hand over the Carburetor (air box hose area). It will run for a sec then die (like it is running out of gas) I need to know the factory carb settings and if anybody has any tips. I have cleaned the carb, changed the plug, gas, and 2 stroke oil. Bike is 100% stock. I am lost and need to call in the experts (before I give it to the shop and empty my wallet).

Thanks!
