Ok I have a 2000 model banshee was starting up fine but didn't really have any power so we got to looking and it didn't have an idle pin on one of the carbs so I got the pin we put it in and adjusted carbs , and it ran for a second and then it died and won't start back up?! Iv checked and it has fuel and spark what can be the problem here? We've messed with it for days checking everything even took carbs apart and cleaned them any info would be much appreciated !
