Hello. I just recently purchased a 98 blaster for my son. I am currently having some problems with it. It came from a young kid who apparently thought he was a mechanic. When I first got it it would not fire so I replaced the coil, cdi, voltage regulator and just replaced the entire wiring harness. It is now firing but will not stay running. Someone has cut out the tors and took the oil tank off. They have also replaced the stock carb with an OKO 30mm. We believe we have it narrowed down to a carb issue. I do not know anything about these carbs and was wondering if anybody could give some common porblems to look for or any helpful advice as it would be greatly appreciated. My son is ready to ride and I dont know what else to do lol. The bike has great compression and will only run for a couple of seconds.
