Rustyred 58 #1 Posted December 13, 2017 Hi y'all, I can't figure out what bolt or hardware to use to connect the carburetor to the engine block on my C 81. Does anyone have input? What size of bolt, and does it get lock washers or washers or what? I simply can't find it in any drawing. With thanks, Rustyred Share this post Link to post Share on other sites

pfrederi 17,147 #3 Posted December 14, 2017 Take a hacksaw and cut a slot across the head of the bolt. It is quicker to spin it in with a screw driver rather than the 1/6 of a turn useing a wrench. 3 1 Share this post Link to post Share on other sites
