Open vacuum port?

BigAl331 · #1 07-17-2009, 01:14 PM

I was looking over my '82 Johnson 150 and found an open vacuum port directly below the bottom carb. I downloaded a manual but I can't find anything about the vacuum hoses. Does anyone know what goes on this port? Is it needed or can I cap it off?

The one below the carbs goes to the air damper cover.
Look on the back of it and you will see another nipple.

Or are you running without the cover installed?

Not sure what you are talking about. Where is the damper you are talking about?

Al,

Can you show us a picture of it ?

The carburetor intake.
The flame arrester.
The big cover that takes up all the space on the front of the engine.
Hell, I can't *****, I don't even have a picture of mine.

I just tried to take a picture of mine and you couldn't make out anything useful as to the routing.

It's less than 4" from the nipple your taking about.

There is nothing in the carb cover that moves so why need vacuum.

I plugged it with piece of hose and screw.
