maybe a throttle adjustment or dirt, linkeage stretch, plugs,

 

I changed the plugs already. Most motors have some sort of idle adjustment, I can't seem to find one on this motor. I think I am going to be able to get a service manual, but I am not very mechanically inclined....

 

put the ser # and if in google add diagham. should show you where its at.

 

Look at the end of the twist grip throttle handle. There should be a protruding knob that will allow you to adjust the idle linkage. If my memory is correct you turn that knob clockwise to increase the idle speed. Mike

 

I looked it up think its #6 in the handle like mikes says.

 

Mike and bountyhunter, thank you both for the replies. I should have noted that I did try the idle adjust on the tiller handle, it did not seem to make a difference. I was thinking that there might be an internal one (under the cowling).

 

what kind of gas are you running? E-Free I hope. Also, did you change the fuel filter? Is it carburetor model?

 

Pike, there is a low speed fuel mixture screw on your carburetor. PM or text me your phone # & I'll give you some guidance on how to properly check & make adjustments. Mike Bruns 419-305-8111

 

The gas I use has ethanol in it, I do treat it with a Mercury fuel treatment product. I only use the motor for about 5 days a year and always run the gas out of the carb when I put it up.

I ran the motor at WOT for about 15 minutes with no issue, that leads me to believe it is not a fuel issue.

 

mike just a thanks from all the guys you,ve helped out over the years. thanks again.

 

Had the exact same problem with my 93 Evinrude 9.9. Put 2.5 gallons of fuel in the tank and a 16 oz bottle of Seafoam in the gas tank. Ran it wide open for 10 minutes and let it idle down. Repeat, repeat, repeat. After about 80 minutes of this I came back to the dock and it idled fine. Fixed the problem. You can also put some Seafoam directly in the carb for faster results. The engine was new to me and had sat for about 6 months. Nothing Seafoam couldn't fix. $7 fix. I work on my own stuff, but no need to start anywhere else other than a good clean out.
