I have a 2003 Polaris 330 Magnum 4x4 with a Mikuni carb. The air fuel mixture screw is broken and my local Polaris dealer says the company does not offer that specific part because it is part of the emissions control. I have checked the parts breakdown for the unit and it does not show the air fuel mixture screw. Any idea where they might be available? Thanks

 

Try some other shops(that have been in business for awhile) if they have some old Mikuni 4 stroke carbs that they would sell parts off of or the whole carb CHEAP!! I accumulated a few carbs in various conditions over the years and used em for parts and would sell parts off of em at about 1/2 price of a new part! Most fuel/air mixture screws(under the factory block off plug) are the same on Mikuni carbs. Try Ebay too, if you can get one cheap enough or cycle salvage yards if any are around your area! Not sure if K&L Supply or Parts unlimited would have the fuel/air mixture screw in a kit,BUT might? Hope this gets you started.The block off plug is mainly just to keep people from messing with the carb idle mixture setting which a lot of times is really too lean! OPT

 

Thanks for that info, I will check out some of the local shops
