Ok guys I've had my CEN Racing CT-4s for about 3 months. Its not starting anymore and I have looked through many things...I believe it is my clutch bell or carburator. I took apart the engine and nothing seems to be broken internally...the piston is still in emaculate shape, no burn marks or anything. Just wondering if any has had this problem before. Oh an the glow plug is brand new. Lemme know
