I have a 91-92 blaster it ran for awhile till my idiot brother got ahold of it. I've had it running for minutes here n there but the dang thing won't stay running . I took it all apart cleaned it all nothing appeared to be wrong with it . This is my first quad but when I kick it now itl run for a few seconds n die I'll kick it again n again n the same thing happens. Every know and again when I kick it a blue flame shoots out the exhaust but I only have half the exhaust on . Help please can post vid or pictures if that will help
