My friend rode my Blaster down to the end of the block and back. When he got back, pulling into my driveway, it died. He got off and when I got on and tried to start it, it won't start or even try to start. We tied a rope from his 330ex to my Blaster. He pulled me around the yard and it will start and run fine until I let off the throttle, when it promptly goes dead. Got gas, air, and spark. I am thinking my pilot jet is clogged. What do you guys think?
