I was putting a bi-turbo exhaust on to my Puch magnum mk11 (1979) and the screw that comes out of the bottom of the engine broke. It broke off flush only leaving 1/4 of an inch or less sticking out. How do I fix that? I can't even put my old exhaust on because there isn't enough screw left to make a seal.
Please help, my girl is out of commission until I figure this out, which leaves me with no transportation.
Thanks all!
