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.

      Thanks for the feedback friends, looks like about a $3,500 surgery and yes, the professionals say what you have all said that a second ACL injury happens often in the other hind leg as a result of over compensating....

      Here is the prize list for this years contest. Lots of food and drinks available at the contest also. Booya will again be sold on the ice provided by the Little Canada Fire Department.   My apologies, I cannot figure out why this will not present the correct way.   Fishing Prizes 2017.pdfFishing Prizes 2017.pdfFishing Prizes 2017.pdf

      The warm weather has opened up some cracks and you can watch the road operators earn their money.  New roads were popping up quickly and bridges were set and the day went off without a hitch.  Thanks for good quick work so we could all fish today. BTW....fishing is staying pretty solid.....Here is today's report

      Chuck was a real, authentic, honest to goodness good guy.  He loved being on the radio and you could tell.  Radio lost a friend.  RIP Chuck
