I have a 1939 f 20 we got it running, but at full
advanced. It seems to run rough? I can retard
spark a little and it smooths out. Can I adjust
the coupler on the front of the magneto? If so
which way would I need to rotate it? If I'm
looking at the front of the magneto? This was
my father's first tractors and hasn't ran in
about 30 year's so firing her up the first time
and seeing his face was well worth the effort!
