    Take some time to watch Cajun’s series of videos explaining these ignition systems. He’ll walk you right thru it from start to finish. He also has some vids on carbs which might be worth checking out.

    Part number for the fuel filter is 379635 or 594034. Several on eBay right now.

    Not sure if those are superseded numbers or maybe just for the filter? but just going by the manual page the part number for the whole assembly is 277187, and ebay does have those also, if you decide not to do Mumbles nice fix. Or a member might have one for sale.

    Oops -those are Johnson numbers. Don’t know if they are the same as Evinrude. I would suspect they are interchangeable.

    OK so I a at the point where I know the carb needs attention Sure enough when I took the bowl off I found that the inlet was blocked. That’s fied but now I’m doing the rest of the carby.

    I’m using this as a guide.

    But not finding the high speed nozzle easy to remove and not wanting to damage it wondering if I should leave it. Any tricks to getting it out or alternatively cleaning it in situ?

    clean it with carb cleaner and blow dry with air pressure …. if you don’t have a compressor buy a can of keyboard air cleaner at the Dollar store.

    if… I say if …..you have a very thin stiff wire smaller than the diameter of the jet and the hole is plugged just clean out the passage with the wire to poke out the crud if any

    you should see light from the crab bowl when looking into it

    at this stage I would not recommend you try to unscrew it without the proper tool

    Are you trying to remove the fixed high speed jet, or the carb nozzle that is threaded into the center of the upper carburetor body? Like others have said, trying to remove the fixed high speed jet without the proper jet screwdriver usually results in damage to the jet and the threads….So, it may be best to soak the carb bowl in strong carb cleaner. Sometimes you can pass a small pipe cleaner through the fixed jet to help clean it also…
    The main body nozzle simply threads into the body…Using a large screwdriver should easily remove it….If the nozzle is stuck also, I wouldn’t risk damaging it by forcing it out with the screwdriver. I would soak the upper body in strong carb cleaner as well…

    Yes I have a new fuel line, have thoroughly cleaned the valve / tap that screws into the tank (which was full of crud) and have ordered new inline fuel filter.
    I’m not satisfied that my tank cleaning was adequate. I think I will use ‘nuts and bolts’ as per this video. Is that a reasonable way to provide the abrasion necessary to remove all the crud?

    Well I’ve done that now (cleaned out the fuel tank) and still no start. So there is nothing blocking fuel precarby.
    .
    I also cleaned out the carby with carburettor cleaner and reassembled – no I didn’t have a carby kit.
    As per this page: https://outboard-boat-motor-repair.com/Evinrude%203%20HP%20Lightwin%20Outboard%20Boat%20Motor/Evinrude%20Johnson%203%20HP%201952-1967%20Carburetor%20Tune-UP.htm

    When the fuel is turned on, should fuel rush into the carby? Doesn’t seem to happen this way for me which makes me wonder if somehow the carby still has a blockage (I know the tank is clean and the tap/valve is not blocked)?

    Checked sparks and have them on both plugs.Could the order of the plugs be out? What is the best way to be sure each lead is on correct plug? Could the spark be of inadequate strength and will one of these tell me if it is so? https://www.ebay.com.au/itm/Car-Tool-AZ-Ignition-Diagnostic-Adjustable-Spark-Plug-Tester-Wire-Circuit-Coil/283667078200?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D2%26asc%3D20160908110712%26meid%3D24864db496fe47bfb2063e807026e3b6%26pid%3D100677%26rk%3D3%26rkt%3D30%26mehot%3Dnone%26sd%3D362706144982%26itm%3D283667078200%26pmt%3D1%26noa%3D0%26pg%3D2386202%26algv%3DSimplAMLv5PairwiseWeb&_trksid=p2386202.c100677.m4598

    did you do a blow test on the carb ??

    is fuel delivered to the carb if you disconnect the feed at the carb inlet ?

    is the choke plate working ?

    do you feel suction on the carb face if you put your hand n front of it while you pull the start cord ?

    try a tea spoon of gas in each cyl ,,,,install the plugs and try to start…does it at least sputter a bit ??

    With the fuel line disconnected from the carb, there should be a good flow (not gushing) when the valve is open. It doesn’t take a lot of fuel to run these little motors. With the carb empty, if you blow in the fuel intake, air should pass through. If not, there is a blockage or float is stuck closing the valve. I usually test before re-installing. Right side up, air should pass. Upside down, no air should pass.

    The front-most coil feeds the top cylinder.

    Remove the lower hex drain plug from the carb and open the fuel valve….Flow should flow out of the carb if the lines/valve/inlet needle seat are OK… Did you inspect/clean the carb fixed high speed jet?
