Cold Weather Starting TR3

[Franz and Monica Bachmann <fmjm@cyou.com>]

I would like to tap the collective wisdom of our list.  The TR3 is very
difficult to start now that the weather has turned cold.  What are some
of your suggestions.  I'm afraid the starter won't last if I continue
cranking as I have.  Once it starts and warms up, it's fine.  I think I
have the choke adjustment set properly.  Fuel mixture on carburetors
must be correct because I have no smoke or stumbling upon acceleration.
Thanks in advance for your help.
