Has anybody ordered the Carburetor Stock RuiXing for Honda Clone and Predator 212cc from OldMiniBikes Warehouse? Their website says it's a stock carb that has not been altered or changed, but when I asked their online tech support if it had an adjustable idle screw since I couldn't tell from the picture, I was told that the carb didn't come with any idle screw. I was informed that the idle screw had to be purchased separately. Does this stock carb really come without an idle screw?
