Bought the kid's a Predator 50 this summer. After about the first month it becam a pain in ther @ss to start. You have to crank & crank for several minutes with the choke on before it finally goes. Then it runs fine. Anyone else have this problem? Could this have anything to do with removing the little metal "tab" on the cdi box?

 

Ck the air adjustment screw (small slotted head above the idle adjuster). Turn it both ways until you get the highest idle, then adjust the idle back down with the idle screw. Clean the spark plug.
