This is a Johnson CD21A
It has an adjustable low speed carb needle above the throat of the carb, but no hole in the hood to access it. And a brass plug screwed in to the bowl of the carb, where the high speed needle should go. This plug sticks out of the body of the outboard just below the hood and there are marking on the body showing how to adjust a needle lean or rich, but like I say there is no needle, just a plug.
Is there supposed to be a high speed needle on this motor?
Why is there no access hole in the hood for the slow speed needle?
