you could try putting jumper cables on it to help with power supply to ignition, it's possible the cold engine cranking is lowering voltage and weakening spark! and it may help with the increased cranking speed!

When I have had this problem with my 8-N I have placed a heat light on the carb (I use one of those Aluminum Hooded Flood Sockets) Leave it on until the carb is about 70 degress or so..about 30 min if real cold. Then...contrary to what everyone says I use a can of spray starter and spray it in the intake. As I hear the engine fire, I keep the spray going and the engine going and it gradually begins to fire on all 4 cylinders. Voila! Works everytime if I have a fresh battery and fuel flowing freely through the filters! Hope I haven't misled anyone and I know this may not be the best for the engine but after all ...it's a '49 8-N:tango_face_devil:

I will agree with other comments here. I have a 49 8N, and use it in any weather, started and ran great at -11F last week. It is original 6V system. Keeping points, cap, rotor and wires in shape for strong blue spark is key. It is also very easy to flood. I do not choke more than 1 or 2 revs. If flooded, I find best thing is remove intake hose from carb and walk away for an hour or two. Mine is always in an unheated barn, no supplemental heat ever needed to get it going.
I also agree a lot of carb and fuel parts get replaced due to weak spark in these engines. Just make sure you have flow out the carb drain and get the ignition right.

Lots of information missing-such as information about the electrical system (original 6 volt or changed to 12 volt). Inside a building or sitting outside? Does it run for a couple seconds or a couple minutes?

The "glass thing" is the fuel bowl. Assuming you have a fairly original fuel system, you have three screens in the fuel system. All three of those screens need to be clean for proper fuel flow. A good way to test the system is to put a can under the carb, remove the large plug at the bottom of the carb, and then open the fuel valve on the tank. You should get a good steady stream of fuel after the carb drains. If the flow of fuel slows down significantly after what is in the carb is gone you have a fuel system issue.

If the fuel flow is good then start troubleshooting the electrical system.

Thats a great tip - Thanks!

Thanks for your advice!!

sounds like gas valve turned off or low volume gas in tank.
