35hp Evinrude High RPM problem

[daniso]

I have a 1996 Evinrude 35hp (3 cyl) with a problems running at higher rpms<br />(above 1/2 throttle). It runs fine for a while and then suddenly dies<br />or goes back to idle. It can then sometimes be revved back up again<br />but not always. It is always possible to start it again if it has died.<br />I've changed the fuel filter and the spark plugs with no effect. I've also <br />tried to pump the bulb while accelerating but with no effect.<br /><br />Any ideas?

Check power pack and fuel system for air leaks.

Unless it's a VRO issue or an overheating problem, it sounds like a carb or fuel injection issue (depending on what you have). On a carburetor model, your symptoms could indicate a clogged high speed jet. Make sure you are running the right fuel mix (50:1) with fresh fuel and TCW-3 oil. <br /><br />(I don't think the 35 is a three-cylinder model, is it?)

It's a "Elan" edition, 3 cyl with separate carbs and separate coils for each cyl.<br /><br />/d
