    Rough running Evinrude V90

    I will look for it at the store. I feel like my tester wasn't making the best connection. It's running pretty good now. Just has a flat spot as it revs, maybe between 1500 and 3000 rpm.

    Rough running Evinrude V90

    Pretty sure I have the fuel set up right. Ses to idle nice now, and it will Rev strong. But there is still an ignition miss and it looks like ignition is intermittent. When I use a timing light on each cylinder it indicates no miss at any time. Soaybe the spark is not strong enough or the signal...

    Rough running Evinrude V90

    Starts mint everytime. I feel like it's something super minor that I've been missing. I cleaned the 2 ignition grounds that were on the painted surface last night. Going to fire it up this evening. Fingers crossed. It should run better than it does in the driveway. There is definitely an...

    Rough running Evinrude V90

    This evening I was inspecting some of the wiring. The power head is painted black. The ignition module on each side of the motor were grounded to a painted surface on the power head. I cleaned them up and put them back together. It was too late to run it. Would it makes sense that if these were...

    Rough running Evinrude V90

    Ok that's good advice. I think I might try that. I will get all of the throttle linkage set up and try it on the water. Starts up fine every time, and yes when I have the timing lever pushed pretty much all the way back it seem to idle ok.

    Rough running Evinrude V90

    Do the reed valves need back pressure being in the water to help them operate correctly?

    Rough running Evinrude V90

    Compression is good all around. It's an Evinrude factory remanufactured unit.

    Rough running Evinrude V90

    I have been using a hose attachment. Is it different when it goes in the lake? Also if it is running lean I don't want to hurt the engine by running it like that.

    I did. It is in its place. Pulled the flywheel just to make sure. There is no adjustment there is there?

    Rough running Evinrude V90

    Ok, went through the carbs. They are mint. Went through art fuel lines. Synced throttle linkage. She still runs rough and misses. Sounds like it's getting good fuel. The bulb now gets hard and stays hard. This leads me to ignition, correct me if I'm wrong. It looks to me like the timing is too...

    Rough running Evinrude V90

    Went through the fuel pump. It seems to be right in every way with no defects in the diaphragms. I can pump pressure in the bulb with the outlet to the carbs capped off. When I connect the carbs I can't get it to pressurize. At least that's what I have found this far this evening. There is a...

    Man I have gone through everything. Only thing I haven't done is replace or kit the fuel pump. I am going to inspect it heavily this evening.

    Rough running Evinrude V90

    I have ordered a kit and a whole new pump as well. I will do the kit first and if it fixes it I will return the pump. Going to inspect the pump a bit better this evening.

    Rough running Evinrude V90

    Right. I am suspecting a leak in the fuel pump. Going to inspect the diaphragms more thoroughly this evening.

    Rough running Evinrude V90

    Carburetors looked ok. There was some varnish in the float bowls. I did not remove the Jets as I assumed, being that they are the factory carburetors that the Jets are correct. I did squirt carb cleaner through each oriface to make sure they were clear. No problems there. Needle and seat seemed...
