Wisconsin VF4D Magneto

Brian Dan · Nov 9, 2011

My Wisconsin engine was running just fine until the magneto filled up with engine oil. The magneto now has no spark.
Is there a seal on the magneto?
From what I have found out the oil is comming from excessive internal pressure. The breather may be pluged up.
I do not have a manual laying around to look at.
Thanks.

VF4/VF4D may have eather a Fairbanks-Morse or
a Wico magneto. Both have an oil seal at the
shaft end, behind the drive gear and impulse coupling. Magneto parts are redily available,
from many advertisors in "Antique Power", "Gas
Engine" and other hobby magazines. However, first
I would check this, Y/T website, as they have
many magneto parts. Look in "Electrical", by
magneto make and model number, not tractor make.
