I mentioned the importance of a functioning thermostatic flapper valve in northern climates, but it is still important even if you live in Mississippi. Unless you live where it stays 180 degrees F, it will reduce the amount of liquid gas from falling out of suspension of the air/fuel mixture which will cause undue wear.
