2006 idles too fast 6 hp

[newbytoboats]

I have a 2006 Mercury 6 HP that idles faster than I want. The only adjustment I can find is a spring loaded screw on the carb. I have backed it out to where the screw doesn't even contact any more and it still runs too fast. Is there any other adjustments I can make? Cause I just can't find anything else.

What speed do you have it idling at

Book calls for 1300 neutral and 1100 in the water in gear.

The pilot mixture is set first and then the idle.

Do you have the service manual 90-857138? If not, see my message to you in Notifications at the top of this page.

What is your engine s/n?

The s/n is ORI56203.
I don't have a tach so I don't know the exact rpm. But it seems to slam into forward and reverse and goes faster in gear than I want to troll.
I found the service manual you refered to. Thank you for making that available to us.

However, I didn't find anything in there that would help me. Pehaps I'm looking wrong.

If you have the manual I mentioned above, you will find the idle mixture and idle adjustments under Section 3B, page 6. It clearly shows you the two adjustment screws.

Thank you very much for that.
The idle djustment screw is completely out to where it doesn't make contact. And it's still faster than I would like.
So I guess that means I have to change the pilot mixing screw.
So do I screw the idle adjustment screw in (thereby increasing idle speed) first so I have some adjustment to play with before attempting to adjust the pilot mixing screw?
I really appreciate your help.

I forgot to add that the lake where the motor is now is about 5000 feet higher in altitute than where it used to be operated.
I'm sure this makes a difference and is probably the source of the problem.
