Hard start old Johnson outboard

3 posts in this topic

Okay guys, here's the story. Brother has a "classic" 1975 9.9HP Johnson. It's a killer to start! Once it's running it seems fine, but low speed idle is not great. Seems to be very sensitive to choke/no choke at starting time. Any ideas? Should I just try to buy a totally new carb? wink.gif

I'd check the compression and spark first, then rebuild the carb with a new kit, along with new plugs, and filter.
