I just got back from a 4 mile run on the back roads with betsy and she runs well.(Boy does this takes me back).outside temp was 19 degrees here this morning.Never shut her down the highest running temp i got on the new gauge was 165. Any one got any ideas why she does not top off at 180+-. maybe wait till summer. my son in law has one of those laser pointer things.He will be up for Easter.Real luke warm heat.
