I`ve run a 6bbl. a long time in all kinds of weather.
How COLD was it?
I see people with coats on?
Check all the usual stuff but its probably the intake manifold.
In cooler weather{on mine 60* was when it starts} the air is cold and the fuel does NOT stay in suspension making all those hard 90* bends in the manifold.
Try NO fresh air,if you have it.
