I recently bought a Johnson 9.5 hp outboard from someone on Craigslist. The previous owner said it ran but has been sitting a few years. Went and got new gas for it, tried to start it and nothing. Wouldn't even turn over. So I poured gas/oil mixture down the carb and it started on the second pull. But died out after a few seconds. I was getting gas from the tank to the bowl in the carb. Took the carb apart and cleaned it up good, reinstalled it, and still no luck. The only way I could get it to run was to keep pouring the fuel mixture right down the carb. Any suggestions?
