[AT] Hot vs. cold Spark Plugs and a different perspective

[Grant Brians]

Larry's statement about the D16 for a hard working engine is the reason why
I have D16's in all of my Oliver tractors - we work the tractors as part of
the business - no idling along in a parade or driving from the backyard to
the front.... So all of the discussion around hot plugs on the list right
now is merely theoretical for me! LOL.
     We use gasoline tractors for cultivation, pulling trailers, harrowing
and many other applications. We also use diesel tractors. In reality, for us
we find that both are useful and function the way we assign them.

IMHO, the D16 is too cold of a plug to use in an engine that isn't being
worked pretty hard on a regular basis.  That's the plug that is recommended
for my restored "trailer queen" that doesn't get any more work than driving
in a Parade of Power.  The plugs would carbon up while idling, so I changed
to D21 and no longer have the problem.

Thanks to everyone for their input.   I'll certainly try the D21 spark
plugs, since I do have Autolite plugs in the tractor right now.  Like you
said, it's cheap enough to try.

I was leaning towards a fuel line/carb issue, except that I have just
recently rebuilt the carb.  I may try a good cleaning today, with new spark
plugs, and see what happens.
