    Have you checked the pick up screens to see if they are clear? How long are you letting it run for? It can sometimes take a few seconds to start flowing when on the muffs.

    That’s looks like very old gas to me or it has been contaminated by something. Get rid of it and start fresh. And take a good look at your fuel line. It may be breaking down internally.

    Yes they will make a difference. They should be the RJ8C I’m a fan of NGK and that would the BR6S I believe but you should double check if you go with NGK

    Lower unit filled with grease

    You could try blowing most it through with compressed air. Use a rubber tip blow nozzle on a blow gun in the top vent and push it out the bottom drain.

    I agree No one is forced to answer your questions and if someone has had enough they are free to jump off the train at any time. Best

    1974 Evinrude 25hp wont run.

    I would shoot for 650 to 700 rpms while in gear and not tied to the dock. But that just me.

    1991 evinrude outboard is this normal?

    I’m in agreement with all of the above. Let it run for awhile and get up to operating temp before worrying about it to much. Everything may just work it’s self out fine.

    1970 25hp deceleration after run at WOT

    No need to worry about timing marks. You are correct the light will stop blinking if you drop a cylinder. It sounds like you carb was in need of a good cleaning and you may find that’s what the problem was. Best

    1974 Evinrude 25hp wont run.

    The mag plate is moving back and forth because the coil is to close. The flywheel magnets are dragging the mag plate. It doesn’t need to be physically touching to be to close if that makes sense. As stated line in up with parallel with the flats on the mag plate.
