I just bought this motor. 1984 90 hp Evinrude E90 MLCRD It has the VRO option (there is a seperate tank for the oil.) The previous owner obviously had some problems with it; the spark plugs and coils are new. Previous owner ran it "a couple of times over the last three years." So, before I ran it, I siphoned old gas out of the tank and refilled with new gas.<br />Problems:<br />The engine is a little difficult to get started and once it finally starts the engine will not idle without the fast-idle lever up. (This makes it rather difficult to get into gear!) Once I get it into gear and slowly accelerate, the engine "misses" a little. ...as if it isn't hitting on one of the cylinders. <br />Once I get the engine up to about 3000 RPM (about 25 mph for the boat) the engine will slowly sputter down and die. If I wait about 5 seconds, it'll start back up again. Sometimes, it'll be sluggish to crank over when this happens. (I have a brand-new battery.) It'll run fine as long as I keep the RPM below about 3000. The engine is not getting excessivly hot and there are no buzzers or horns sounding. The tell-tale jet is strong. There are no funny smells or sounds. There are no fluids leaking in the engine compartment (that I can see.) All the linkage seems to be working fine. <br />What I've done so far:<br />Replaced the fuel filter. Replaced the fuel line from engine cover to tank (including the bulb.) Removed, flushed, and re-installed the gas tank. I've checked the tank vent; it's not blocked.<br />What do I do now? Is this a common problem with an easy fix?<br />Any and all help would be appreciated.<br />KS in TN
