[Farmall] "H" running a little rough

[E. John Puckett]

and if it is still a magneto rather than a distributor, the cap o top is 
also a suspect.
 If wires are old, they may be drawing moisture also. 
 "breathable cover similar to what cars are covered with will probably 
help,
 if no cover try parking it with the distributer/magneto on the downwind 
side, usually to the east.
