    "Hello, can anyone tell me if there is another way to set the wide open throttle timing without a test wheel or tank? Thanks"

    What I do is just remove the plugs and leave them on the wires and ground the plugs so you can still see them spark.
    That way you wont hurt you or your power pack from a plug wire hanging in mid air!
    I then just use a timing light and turn the engine over with the starter and set the timing to factory spec.
    Some folks retard the timing by 4 degrees when using this method but I do not with mine as it always gets high test gas and has never had any problems.
    That info should get you into the ballpark!

    for Johnson/Evinrude


    Joe
    ------------------
    &#40;Timing At Cranking Speed 4°&#41;
    &#40;J. Reeves&#41;

    NOTE: If your engine has the &#34;Fast Start&#34; feature&#34;, you must disconnect/eliminate that feature in order to use the following method. The &#34;Fast Start&#34; automatically advances the spark electronically when the engine first starts, dropping it to normal when the engine reaches a certain temperature.

    The full spark advance can be adjusted without have the engine running at near full throttle as follows.

    To set the timing on that engine, have the s/plugs out, and have the throttle at full, set that timer base under the flywheel tight against the rubber stop on the end of the full spark timer advance stop screw &#40;wire it against that stop if necessary&#41;.

    Rig a spark tester and have the gap set to 7/16&#34;. Hook up the timing light to the #1 plug wire. Crank the engine over and set the spark advance to 4° less than what the engine calls for.

    I don&#39;t know the full spark advance setting your engine calls for, but to pick a figure, say your engine calls for 28°, set the timing at 24°. The reasoning for the 4° difference is that when the engine is actually running, due to the nature of the solid state ignition componets, the engine gains the extra 4°.

    If you set the engine to its true setting at cranking speed, when running it will advance beyond its limit by 4° which will set up pre-ignition causing guaranteed piston damage! You don&#39;t want that to take place.

    No need to be concerned about the idle timing as that will take care of itself. The main concern is the full advance setting.

    Be sure to use your own engines spark advance settings, not the one I picked out of the air here in my notes.

    Default I have a 2 cylinder Johnson 25

    I have a 2 cylinder Johnson 25hp. Need to know if there is an adjustment to get better engagement of teeth on starter to flywheel. My motor recently started to not engage properly at times.

    Thanks.

    Dunno what this has got to do with adjusting timing !!
    You should start a new dicussion.

    usual reasons for a starter not engaging properly are: discharged battery, poor connections, bad contacts in solenoid or bendix not running freely.
    Bad connections are responsible for a very high %age of starting problems.
    Checked that the starter motor is secure?
