No, I did not think to specifically look for a thermostat in the
cooling system when I did the installation (so, following the standard
unwritten rules of Usenet, everyone is now free to insult my
intelligence, question my judgment, and/or call my mother's virtue into
question. lol.) In any event, I have discussed the situation with
Lockwood and they assure me that nothing is out of the ordinary with
the temp. They said that they barely get 120 deg of water temp on their
Air Cams. The gentleman I spoke to did warn me to make sure that the
minimum oil temp was being maintained. He also mentioned that the
chatter may very well be a result of carbs that are out of sync. That
was on my "to-do" list already so I'm hopeful that syncing the carbs
will take care of the matter.
