[Farmall] Spark plugs and Cubs.

[George Willer]

Dan,

Your observation isn't politically correct.  It is expected that you will 
badmouth Champions, since we have all been coached that they are junk. 
:-(   Nonsense!

As I'm sure you know, the fault isn't in the brand of the plug... it's 
because they were fouled.  It's just as likely to work the other way around 
within the same heat range plugs.  It isn't a mystery at all!  If the engine 
fouls plugs, the Champions will do the same thing soon.  When that happens, 
put a new set of ACs in and you will see a big temporary improvement!  :-)
