I have an EZjust carb mixture screw. On my trip to Florida I checked the bike when I stopped for fuel and saw the screw laying on the engine case. The spring and washer are laying some where on I75. The o ring is still in the carb so I stopped in at a shop here and talked to tech who gave me what I needed. Has anyone else ever lost their mixture screw. I have thought about putting some nail polish on the screw to bind it in.
