[Farmall] "H" running a little rough

[Tim Savelle]

The guy I bought my 1949 "H" from kept it in a nice, enclosed shop with a
concrete floor.  The day I checked it out, he hit the starter switch and it
fired up immediately....and then "purred like a kitten."  I don't have a
nice, enclosed shop (yet), so my "H" has to stay outside for the time
being.  We've had 3 or 4 days of rain and chilly, damp weather this past
week.  The tractor is now a little difficult to start (doesn't "catch" as
quickly), and it runs a little rough until it warms up.  Could having to
stay outside with constant exposure to the dampness cause this?
