I am having a problem starting my banshee. it has been sitting for about 8 months. with a little help from some carb cleaner it finally starts. it will not idle at all. it fires on one cylinder ok but is very speratic on the other, i have cleaned the living hell out of the carbs and still my problem persists. people have suggested that i have a vaccum problem and others have said that it might be a cdi unit. also when i give it throttle it sounds very throughty and the rpms dont increase all that much. It is spitting alot of oil out of the pipes and and spewing alot of smoke. any suggestions or tips would be greatly appreciated
