This kit comes with both 1 11/16 and 1 3/4 main body to base plate gaskets so it will work with 650, 750, 830, 850 and more. This kit does come with a 5.5 power valve . If you would like a 3.5, 4.5 or 5.5 power valve instead please advise us prior to purchase so we can swap it out.
Both the metering block and fuel bowl gaskets are the blue reusable ones as well as the main body to base gaskets and carburetor to intake gasket. This kit also has nylon fuel inlet fitting gaskets, nylon needle and seat nut and screw gaskets, rubber orings for the mixture screws and an extra set of paper needle and seat gaskets are included for float adjustments .  This kit also comes with a pair of 30cc accelerator pump diaphragms and Viton tipped .110 needle and seats. If your carburetor has a 50cc pump on the rear please advise us prior to purchase and we can exchange the pump diaphragm for you.
