Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • johnson 1969 55hp carb setting up

    my johnson runs fine, but i can here a poping when open the throttle up,

    on the carb, there are 3 injectors, with the front cover on, only the middle injector is avalible to access and it has up or down twist to adjust the mix,

    does the other two injectors top and bottom, have to be done up tight or do they need setting as well?

    You need to get yourself an OEM manual.

        By injectors, are you talking about the holes in the carb cover? If so , remove the cover assembly and it will expose the carb throats, have someone run the engine at WOT and listen for the popping. If it is coming out of one of the carbs, you most likely have a broken reed valve.
        You do need a manual, google Ken Cook or check E-bay. Double check your model number against the manual to make sure the right one.

          What he is talking about is the linkage for slow speed carb adjustment.
          There is one hole through the carb cover over the centre carb....the adjusting lever uses that to connect to the slow speed needle and the connection for carbs 1 and 3 needles run inside the cover.
          This makes carb adjustment a PITA and many people drill holes over the Slow speed adjustment on 1 and 3 and pitch the linkage all together.
          The holes allow access to all 3 needles and makes carb adjusting far less frustrating.

          If that linkage is already missing for sopme reason, he'll have to drill the holes anyway....if he wants to go "OEM", he can PM me and I'll send him the linkage. It's been hanging on my boathouse wall for 30+ years....

            You can "lol", which usually means you have no interest in a manual, but it will save you countless hours, money, frustration, and it will avoid irritating people when you use terms that are simply incorrect....like "injectors" and can confuse the people that are trying to help you out.

            Cost you about 40 quid and worth every penny.

              Re: johnson 1969 55hp carb setting up

              thank you all for your help and i am sorry if my words are wrong when trying to explane parts of the engine, as i am a bricklayer i have not much know how of engines,

              but tim you are spot on with what you replyed, that is what i was on about, the three long pin things (that better) that go into the carb, and yes the idle speed is set by the middle one,

              did you say you had some think hanging on your wall for 30 years that could help me??

                No, your best bet is to take yours off and hang it on your wall , too....

                Take the cover plate top a DIY or hardware store and find a plastic or rubber grommet/push cover that matches the hole size where the adjusting lever goes through. Buy three of these.

                Then drill out holes where the other two needles sit.

                Now you can access all three needles independently and without taking off the cover plate.
                It's the only way to really do the adjustment properly.


                Since the engine is dependent on fuel flow for lubrication, you don't want a lean carb condition starving a cylinder for gas/oil.
                You do not need a parachute to skydive. You only need a parachute to skydive twice.
