Hello, I have a 1996 King quad 300 4x4, it would not start at first, charge battery, installed new plug, and changed oil, removed carb checdked and cleaned, foudn no debris, reinstalled, started, but very rough idle, off idle its okay. Will not idle, idles for a bit then dies, will also backfire. Purchased a carb rebuild kit, installed and still doing the same thing.
Found on other threads, the petcock leaks into the vaccum hose, checked with a vacuum pump, petcock leaks, removed from carb and plugged port, still runs poorly, and idle issues still there. removed fuel pump found debris inside, cleaned and out on a fuel filter.
Anyone have any other ideas to try on this thing? Also it fouls the plugs, I think i got the rich running fixed with the vaccum leak.
Thanks for any help or ideas.
