[Mgs] Question about Thermostats

[Matthew Milkevitch]

Hello Listers;

Quick question about thermostats.  Does the MGB thermostat require a small
hole in the outer edge of the thermostat (I"m assuming to serve as a very
limited bypass)??  I have other thermostats that have this feature but a new
one I purchased does not.  I seem to remember some type of discussion about
this at some point.  I can easily drill a small hole in this unit, but I was
wondering what other listers know.

Thanks for the help,
