Re: 1957 Johnson Javelin
i run '55 15 hp rude every week. i use laingsoutboards.com Jim is great to deal with, and doesn't rip you on shipping. there is also twin citymarine at tcmarine.com keep the fuel system original, i've seen to many engines ruined by messing with the system. it's work 50 years why change it. laings, has rebuilt kits for the tanks. you wil have to run it in a barrel or test tank, as muffs don't generally fit.
