Old Evinrude running rough?

[chackett]

I brought an old motor back to life. The Suzuki DT200 in my signature.

I don't know anything about your particular motor, and I'm not a mechanic, but I wouldn't do anything until I pulled those carbs and THOROUGHLY cleaned them. Running seafoam or spraying carb cleaning in the throat of the cab won't cut it.

Even pulling them and spraying them out may not do it. I pulled mine and scrubbed them and scrubbed them, blew compressed air through them. I did that about 5 times. Each time they would run well for one trip and then get gummed up again.

I finally took them off and brought them to a local guy who agreed to soak them in some kind of untrasonic hot bath, and I installed rebuild kits on them. It made a HUGE world of difference.

I would do the other low hanging fruit stuff too .. replace the fuel filter and water separator (if you don't have one, install one) .. make sure you don't have any water or moisture in the tank ..

Good Luck!
