My 1992 Suzuki king quad won’t take gas on throttle.

I replace everything involving fuel and it still won’t work.

So describe what happens ?  Does it cut right out and stop, drone away trying to draw air and fuel, stutter like someone's flicking the switch on and off ? Does it do this sitting in neutral or only under load.

Have you tried it with the headlights on? Does it rev higher with the light on ?

Have you tried a new spark plug ? Have you checked the air-cleaner? Have you checked the exhaust isn't blocked ?

When and how did this start ? Has it been sitting, were you riding it when it started, have you owned the bike for long ?

Sounds like main jet is stopped up.
