The one in the cylinder head was for the idle speed adjuster on early modes. Not used on 1968 models.

I believe the screw is simply missing from the carburetor... as well as I can remember

Here are pics of my 66 Johnson 9.9 (white) and 72 Evinrude (blue). As you can see the 66 has a little fuel hose support bracket that isn't really required and yes, you are missing a screw in the carb.

Thanks Aerocook,
very helpful now I just need to know what type screw this is standard or needle jet type? If you don't mind removing it to see that would help a lot .
The problem I am having is that it will run at idle speed and then bog down when you try to open it up thinking the screw may be the cause.


thanks again CaptQuent

It's a regular screw, There are 4 screws that hold the float bowl on, 2 long ones and 2 short ones, you are missing one of the short ones. If you remove the other short one on the starboard side of the carb you will see what you need. As for your bog issue, when was the last time the motor ran? has the carb been taken off and cleaned recently? Your symptom could be a result of a number of issues but I'd put a dirty carb at the top of the list. I had the carb off of my 66 a few days ago for cleaning and it was a piece of cake, not complicated at all.
