<VV> Thermostats

[lonwall@corvairunderground.com]

Jim - The old rules remain the same - If you we'rnt getting any 
detonation you were not overheating. Unless physically blocked the 
thermostats will always open when they need to. You are much more likely 
to have problems (Including a very short life span) with repro 
thermostats than any original one.
