Yamaha is having issues idling. Runs strong once above 1000 rpm. Just started to do it. Hard to start once it starts its idle issue. I have to pull out the manual choke to get it running again. Sounds like it is not getting fuel. Primer ball is good and ventilation is good. I am thinking carbs are dirty. Any ideas and how to fix it also. Maybe the idle screw needs adjustment. If you could leave me your ideas and directions on how to fix it would be appreciated. Thank you
