2N stalls out on heavy pull

If this doesn't help then the carburetor probably is in need of a good cleaning inside to remove built up foriegn material and or water.

Cleaning the N carburator.
If it is as cold as you say the problem may well be the presence of moisture in one or more places in the fuel system. Water likes to go to the bottom of gasoline and the bottom of the system is at the bottom of the carburator.You will never get it to run untill you get the carburator warm enough to melt the ice and get it out some way. The best thing to do is to take the carburator off and take it inside the shop and warm it up and then take it apart. Remove the big high speed jet needle from the front of the carb. It will be facing down and angled to the back slightly.
Be very cautious about the gas in a closed area and have no source of ignition so you don't set yourself of fire with the gas. The bottom of the bowl needs to be cleaned good and then blown out with compressed air. If you have the right tool to do it you need to remove the high speed fuel nozzle. That is the brass thing in the venturi (throat) of the intake that is pointing down and toward the front. It takes a long socket of the right size and don't try to get it out with a pair of pliers or you may get it so it can never be removed and cleaned. There will be several little holes in the jet that come into the bore from the sides and they all need to be opened with a needle of the right size. The best thing to use is a welders tip cleaner as it will have an assortment of different sizes and one will fit. Always use the biggest one you can get to go into the hole,

Be absolutely sure that the orifice in the bottom of the carburetor just below the point that the high speed needles sits when assembled is absolutely clean and free of all foreign material.
