Missing knob on a 1985 Evinrude 6hp

9 posts in this topic

Hey all,

I have a ~1985 evinrude 6HP. Looks something like this:

In between the pull cord and the choke is a missing knob.

Based on looking at the label, it must have been an adjuster of some sort as opposed to an on/off switch. Anyone know? I have no manual for the motor.

It probably controled how lean or rich your fuel mixture was!?!?!

Ok, that's consistent with what I see here:

Although that is not the same motor. That says "low speed mixture" for the middle knob. So what the heck does it mean? Turn the dial high or low depending on whether I am going fast or slow?

I wish you could easily get pdf manuals online.

That's exactly what it does, for the low speed jet.

Here's a snapshot of what the knob connects to:

Wow, thanks.

It seems like i can use a flathead to adjust it without the knob. Do I want to turn it down when going slow. I will now google...

It depends on how it's running.

I'd spend some time running your motor and see how it runs now. You may not need any adjustment at all.

yeah, I never noticed any major issues. Would this help it stay running when idling? It has some issues with that, but I didn't expect more.

You should be able to set the idel speed adjustment and forget it. Unless you change the fuel/oil ratio it should be fine.

A piece of hose slipped onto the low speed screw will work too.
