[TR] Plug Heat Range

["TR250" <tr250@mindspring.com>]

Bob,

No chart on heat ranges but I did install Autolite 65's last week before a 300
mile trip through North Georgia.   Seemed to work a lot better than my recent
selections.   We've been fouling plugs at low revs for about a year and have
tried several different plugs.   These are supposed to be two (2) heat ranges
hotter than normal.
