Sorry it took so long to find the post slinger, Get a small bottle of Indian Shellac at any auto parts. Your reed cage will have an "o" ring on the engine side, and a peper gasket on top. They work by flexing open on the up stroke to let fuel into the cases, and sealing shut on the down stroke so that mix is forced into the comb. chamber thru the ports. Your oem reeds are stainless steel, and can crack if there is a sudden change in rpms. (IE the belt breaking) Check them asap. If it breaks off it will wind up inside the cases. If you do find a broken reed... Order a set of Boysen carbon fiber blanks at .030-.033 thick. You can easily trace, and cut the blank to fit your cage, and have a quicker response from the throttle, as well as a more stable running top end. Check for a leak around the carb, and cage too before you take it apart. One of those vacuum testers like Shaka made will prove to be you next best friend w/ a 2t. From sitting so long it may have dry seals on the crank.
