    would it help 2 re varnish the magneto 1 of my mags has lasted since first motor[happy time] but others have failed this mag has a definite thicker coat of varnish others seem watery

    Problem is that the varnish needs to be impregnated into the core of the magneto. This can really only be done when it is made, vacuum impregnation would be the best way but I dont think they go to these extremes on the chengines.

    Okay. But if someone put a coat of new varnish on for weather/water protection, would that cause any harm?

    to encase that bunch of wire THING

    just a question for you here bluegoatwoods
    do you think that's just standard varnish used there ?
    for some reason I am thinking it might be a little different mixture ?
    also wondering if there maybe something even better to use
    so as to encase that bunch of wire THING ?

    can't see where any harm would come from an extra coat or two

    have a good day as you -- ride that motor bike THING

    I'm afraid I don't actually know the answer to your question, MountainMan.

    Can varnish affect the magnetic properties of the magnet and coil? If so, then we can be pretty sure that magneto varnish is special, "a-magnetic" stuff. So then household wood varnish would not be right.

    I'll betcha duivendyk would know.

    But anyway, I have doubts about whether a thin coat of varnish would affect the magneto function. And I suspect a thin coat wouldn't hurt and might help.

    But this is not far from guesswork.

    well -- I got a little more interested about the varnish used for magnetos
    looked around -- just a short while on google

    one place said to be sure to use a -- ((-- modern heat curing type of varnish --))

    not sure what that is -- but thinking -- not the standard boat varnish ???

    ride that THING

    As long as the varnish won't melt, I see no problem with it. No matter what it's made of, it won't bother the magnetism, being that it's not metal.

    Oftentimes in the cagers world, I see ignition components saying "epoxy filled" or "encapsulated in epoxy". Again, I'm sure it's some special ignition formula, because JB weld is an epoxy, and I can't imagine that working too well.:cool:

    I use regular houshold varnish on the tesla coils that me and the neighbor build:devilish:

    I don't have one laying around, but someone must have a extra magneto to do a test for us. You
    have to be down south somewhere cuz its flipp'in -24 below here. :ack2:
