bump starts but wont idle

[bigmgt14]

okay so i have obviously a kfx 450. it started great yesterday under its own power. went to start it today and it would not. so i pulled it behind my prarie 360 and bump started it. it idled then i put it in gear and drove it. pulled the clutch in to wait for my girlfriend and it stalled. it wouldnt start under its own power again. so i bump started it. it ran really rough. if i held the throttle in one position it acted as if i were blurping the throttle. and the exhaust smelled real heavy with gas. it had a new spark plug 2 months ago. and a full system check done by the local dealer. the only thing i can think of is it is a bad fuel injector. please help i have a trip planned with my girlfriend on aug. 1 so i need to get this fixed.

bump starting a fuel injection quad dont always work. if your battery aint strong enough to power the pump with it running it sure wont power it. I had this before from a dead battery. bump starting did nothing

the battery was fully charged. the quad is acting like its flooded.

Change your spark plug i had the same issue after the bike sat for the winter i went with the cooler ngk plug compared to factory and its had no problems.
