My Ski Machine came with an 88 200 hp Yamaha, it sat for 3 years and doesnt want to idle without help so I'm gonna clean the carbs. Am I in for any problems or is it straight forward? I've done pleanty dirt bike and snowmobile carbs but never a 2 barrel like these. I bought a small
ultrasonic cleaner and rebuild kits. Anything I need to know???
