An added note: I don't know about the 15s. But the 9.9 and smaller engines did not have a kill switch or button. Those were designed to be killed by low-idle stall. Death by starvation, as I call it, lol. That was a common way of killing small engines back in those days. So if you have no kill button or on/off switch, then the motor is supposed to die at lowest idle. In which case, an issue you might instead be experiencing is that the throttle drops if you don't continually hold onto the control. When you let go, it vibrates to its stalling/kill position--which is not very far from idle/run, so it's not always obvious that is what's happening. I've even had it happen while holding the control, and not perceive it due to the very small distance. Assuming that is the case, I would consider 2 options. A: Accept it as a safety feature and just plan to maintain grip while motor is running. Or B: Tighten the throttle control joints and connections all the way back and into the motor compartment.

The throttle cam follower is supposed to have that delayed contact at the low idle range. That was a common OMC design for single-carb engines. And the timing alignment appears correct. The lowest range of RPM is governed entirely by the timing while the throttle plate remains stationary. The cam follower comes into contact at the timing mark; and the throttle plate is active from that point upward through the rest of the RPM range. That confuses a tradition mechanic because we're accustomed to RPM being governed by controlling the air flow. But on those motors, RPM is (at least initially) controlled by ignition timing.

You remind me of Ray Ramano LOL Комментарий от : Jase McCauley |
what is the actual condition? low idle can mean many problems .. with low idle adjustment ,you will need the motor to have all of what you took off.. does it die when on low idle after about a minute .. my 73 johnson and 79 evinrude both had this problem on low idle when trolling both times .. both solved when i replaced and or rebuilt the fuel pumps .. for you to me and I've dealt with this when I bought the twofur .. bought one got the other as non runner .. tinkered around ..in motor .. nothing obvious .. then read up .. can't remember the name .. somebody's ramblings ... the tiller was out of sinc by 1 tooth .. as you at 7.04 .. BTW plenty retailers quicker and as cheap as ebay ..especially for Canadians... jeez we really need we need to get you a Canucks shirt :) that's half the problem . LOng story short check the basics first before dismantling Комментарий от : Quat Sino |
Do you have a link for the service manual? Комментарий от : David Bragg |
Get a flywheel puller Комментарий от : Bw Yyy |
At 5:10, What is that thing and what is it's function? Mine is broken and missing. Thanks. Комментарий от : raybone3 |
Bro I don't understand why you're disassembling the whole throttle body when it's apparent you have a linkage that needs adjustment I watched it just to see some of the parts Комментарий от : Joerilla Rilla |
Are you certain you know what you need to remove it looks you disassembled outboard but not getting to be able to fix it .. More diagnosis requires. Комментарий от : Chris McCartney |
Have a look at Kodibass Channel he is a JohnyRude expert. . Комментарий от : Chris McCartney |
