<div dir="ltr">Thank You, the shaft bearing wear was also
something that came up in my dreams or pre-sleep last night as well. If the
shaft or bearing wear is bad enough it sure would mess up the point gap,
We went through several magneto's so the rotation issue is a not in play here.
No kill switch. This is the only one that quit working on the tractor. I usually
check for shaft bearing wear but that wasn't on the checklist yesterday for some
reason.. I guess I better print out a check list in the future.
Getting old and forgetful. I used to kind of pride myself in being able to
refurbish magneto's fairly quickly if there isn't something major wrong like a
bad coil or something. When I got this one working yesterday, working on the
tailgate of a pickup, I was kind of patting myself on the back that I still had
my stuff\. Well that BS came to an end real quick when it was
installed. :-) </div>

<div>Interesting... is there any endplay or runout in the magneto shaft that may
throw the points off kilter when installed? It kinda sounds like a low voltage
side thing (kill switch, points, grounding) or something associated with the
installation (mechanical alignment, electrical connection or incorrect rotation
though the impulse probably wouldn't work). <br clear="none"></div>

<div dir="ltr">Was helping a friend today testing out some carburetors and
Magneto's on his 1936 JD B. A very strange thing occurred. I was in charge of
clean ing Magneto's up and getting them to the point that they would deliver
spark manually on the bench. Then we would install them on a tractor and get
the tractor running. I went though one Magenta pretty thoroughly and was
getting really good spark out of both ports on the bench. Install it on the
tractor absolutely no spark. Could hear a really good impulse. We
tried tightening it up tighter and also loosening it up. No change ...no
spark. Blew me away I was getting really GOOD SPARK MANUALLY NOT MORE
THAN A FEW MINUTES BEFORE. W hat in the sawmill would cause something like
that. The only thing we didn't check was to see if the Magneto was
getting grounded properly to the governor. That is the only thing I can
think of right now. What other reasons would cause this strange event???
Really
weird.</div></div></div>_______________________________________________<br clear="none">AT mailing list<br clear="none"><a shape="rect">AT@lists.antique-tractor.com</a><br clear="none"><a shape="rect" href="http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com" rel="nofollow" target="_blank">http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com</a><br clear="none"></blockquote></div></div></div></div>
