2000 King Quad 300 4x4 1987 Quadrunner 250 4x4
I have a quadrunner 250 4x4 and it was working the one day but I noticed it would sputter and cut the engine at lower rpm's but higher rpm's it was fine. The next day it wouldn't start, I bump started it and it started but quickly stalled and backfired. It kept doing this and then it just wouldn't do anything, now when I try it, it sounds like it's about to start but it jus doesn't. It has spark, fresh oil and oil filter, and it has gas. Does anyone know how to fix this or what the problem is?
