Hi I just bought this Banshee about 2 weeks ago and it needed a rebuild. I rebuilt it tonight and it only runs on one cylinder untill I pull the choke, then the other one fires right up and it runs on them both but the opposite side runs crappy(since it is on choke and it doesn't need to be). The carbs are jetted the exact same, everything is hooked up (including the little hose between carbs that run the choke). Plugs were changed and still does the same. Please help!
