As you all saw in the subject my 99 Hero Magestic Panther is having some problems. I replaced the cdi and the carb, tuned it and every thing, new spark plug. But when I go to start it it just runs for a little bit then it dies. And if it does run when I pull the throttle it dies out. Then backfires I've been trying to figure out what's the problem but it's difficult. What are y'all's opinion on this problem?
