    Awesome find Stanley…. THANKS!
    It definitely implies that the engine
    will run in reverse, but I’m not seeing anything
    implying an impulse coupling, but then again,
    I have a hard time finding stuff in the grocery store
    right in front of my nose!

    Tom,

    There’s a Wisconsin RBM ad in the “Inner Sanctom” in the archives. It says the magneto was reversible.

    Dave, I thought I had looked thru those archives a while back,
    but evidently I miss that ad. Thanks!

    Worked on the mounting plate and and coupling today for
    the Bendix mag to adapt to the Wisconsin. Neither are
    done, but at least I have a plan now….. if it works may be
    another story.
    Worked on firewood, dug up flower bulbs, and sadly,
    drained the outboard test barrel and put it away for the winter. 🙁

    I got a old mag in my garage, wilco gear driven, came with some other stuff, I don’t need it if it will help.

    Jim, Thanks for the offer, but for now, I’ll continue with the Bendix, seeing how I’m
    almost done making the coupler, mounting, etc., and it even has spark!

    Okay, I spelled it wrong Wico Model X. probably off a tractor since it’s orange. let us know how yours works out. Jim

    I made some progress on the magneto. The coupler is made, as is
    the new mounting plate, and it’s bolted up. Right now, I’ feel no further
    ahead of having a working outboard though!
    It seemed to have good spark on the bench the other day by just
    turning the armature by hand (without the impulse attached).
    I have to crank the Wisconsin’s flywheel a pretty good clip to get any spark
    right now. The mag seems grounded to the motor okay, according
    to my "buzz box".

    I also believe I got the timing off, as when I had the mag hooked
    up with my "buzz box" determining at what rotor position the
    mag would "fire" to attach the drive coupler in the correct position,
    I must have been turning the magneto the wrong direction.
    I can fix that by drilling and tapping a new hole for the set-screw
    to ride on the flat on the armature shaft.

    I presume that testing this type of mag with my buzz box (9 volt battery)
    would do no damage to the magneto / coil, but I sure got a buzz
    when I accidently touched one lead…… got my attention!

    The magneto still has the "old" condenser yet, as I don’t know what
    to replace it with. It tested at .45 mfd or so. Seems "high" for
    any condenser. I haven’t found any specs as to what the rating should
    be for this mag. The Bendix part number is…….
    10-58224Y
    UPDATE: I went thru the Mertronic manual again, and didn’t see
    my condenser number listed, there was a condenser listed for
    "H Series" magnetos, part number 10-82104, rated at .15 mfd’s.
    My magneto is a model H1-4, so maybe close enough?

    I emailed a magneto rebuilder, but heard no response back.
    If I can’t find the information, I’ll just replace the old mag with
    a .22 cap and see what happens.

    At this point, I rather not re-design a coupling in order to use
    the Bendix’s impulse coupling, but suppose that’s an option.
    Another option (I think) would be to turn the magneto into a distributor
    and hook up with a battery and external coil.
    All for now.

    Buc, have you had the magnet remagnetised? Those pre WW2 motors have soft magnets and after say 90 something years are weaker and require rejuvenation.

    The rotor magnet seems to have strong magnetism as you rotate it by hand.
    I believe the magneto is from the 1950’s, so it probably has permanent magnets.
    If I get a chance tomorrow, I’ll replace the old condenser with a capacitor
    and see if the spark improves.
    If not, I’ll think about how to make the mag into a distributor.

    I changed out the old condenser with a capacitor.
    The mag still doesn’t spark unless you’re cranking
    the Wisconsin’s flywheel at a fair clip.
    It sparked fine on the bench with the impulse coupling
    off, but "flicking" it with your fingers turns it faster
    that slow cranking the Wisconsin’s flywheel.
    I put the impulse coupling back on (took three tries
    to get it right, and that little spring is a bugger!)
    and it snaps and has good spark by appearance.
    Therefore, I’m redoing a coupling so I can hook the
    mag up with the impulse. Hopefully tomorrow I’ll
    have the mag remounted and ready to see if plan "B" works.
    The mag with the impulse on seems to spin backwards
    okay, so theoretically one could "bounce" the flywheel
    off compression to start it….. I hope. 😕

    No "Singing" yet, but does now have "Snappy" spark.
    Got the new coupling made to incorporate the
    impulse coupling on the mag. Perhaps I just need
    to work on the technique, but I’m not sure if I’ll
    be able to pull the flywheel through compression
    and make the impulse snap and hence, fire the mag
    at TDC. It doesn’t help that the motor stand is on
    casters. Guess I better go watch some YouTube video’s
    on starting RBM’s……. I’ve never had the pleasure.
    In the meantime, you can watch my video if you like,
    and any "tips" welcomed!

    Remember, it only needs to "snap" once….. after that it should go on its own, given all the other details are correct..Also, because you are using something other than what was original for spark, I would try to find out if the timing of the spark is correct, as in when it should spark…

    I went out a while ago and tried pulling the flywheel thru compression
    by bouncing off reverse compression and trying to use that bounce
    to help pull thru compression in normal direction. Didn’t work,
    and I almost tipped the stand over. 😮

    I have it all timed to fire at top dead center. Specs say my magneto
    has a 10 degree lag, so from what I understand it will fire at TDC,
    and once running it will fire 10 degrees BTDC.

    Anyone ever try starting a RBM by just grabbing the flywheel with both
    hands and pull it thru compression?
    I need to get the motor on a stationary stand or safely mounted to the
    workbench before I try much more. Also need to put the gas tank back
    together and coat it, now that my "Red Coat" was delivered.
    Tempted to rig up a temp gas tank to see if I can make smoke!

    10 degree lag????

    it should be firing before TDC…not at…
    Make it stupid, retard the timing…LOL

    Just guessing but I know of no engine that fires right at TDC, all that I know of are BTDC, how much depends on the set up…
