I recently had a 2002 blaster rebuilt (bottum and top end) and once it was broken in I went on a weekend trip to Busco Beach. While riding over the weekend my blaster just cut off on me and I can not get it to stay running now. I finnaly got it running again but I can only give it but so much throttle before it will just cut off. Once I put it in first and go to take off it also cuts off. I did notice that there was alot of build up on the spark plug when I checked it but not sure whats going on with it. I have changed the plug a couple times and each time there is lesser build up on it. can any one please help.
