Sorry for the OT question, but I couldn't find a small engine group.

I just pulled the flywheel on my Briggs 18hp v-twin Z-cart. (starter
repair)

Should I clean the armature/magneto contacts with anything besides air
while I have it off, or leave it alone?

Thanks.

Steve,
According to my B&S repair manual do not soak the armature in a
cleaning solution. The armature commutator, if it needs cleaning, can
be cleaned with 000 sand paper. Don't use emery cloth as it will embed
in the commutator and cause rapid wear. HTH, Jim.


Thanks Jim, what do you think about a non-residual, plastic safe
contact cleaner?
if you were going that route then alcohol could work but the manual
specifically mentioned no solutions were to be used. are you sure it
needs cleaning? is anything pitted or burnt/glazed?

I just pulled it this evening after work, so I've not even blown
it off with air and looked close at it yet. I was going to do that,
but my wife came back to the barn and told me we had nasty weather
on the way. (strange weather day here)

It may not need anything more than a soft air cleaning, but I figured
it wouldn't hurt to ask.
