[Farmall] Spark plugs and Cubs.

[Dan Glass]

I would agree with you, but this has never been the case in my 
experience. .   The AC plugs that were taken out were not fouled., they 
looked clean and ready to go back in.  Gap was correct.  I had one guy 
sell me his cub lowboy because of this very problem and he thought the 
cub was junk.  (He didn't know about switching to Champion.)  I found 
out by chance.  I have run that same cub for five years with the same 
Champion plugs and no problems. I even used it today to pull a trailer 
of plants to the field.
