2N Hard starting and drips as out carb intake while trying

My 2N is almost impossible to start when the weather is colder. During the summer months it does not appear that hard to start. After craking it for awhile in the cld it stutters and tries to start but never really gets going. I've tried any where from very little throttle to 1/3 throttle to 1/2 throttle to full throttle. Tried with and without choke and with modulating the choke. After a few minutes no matter what I try I notice gas coming out the the carbyretor intake. Last imte I checked, this summer had good sparl. Waiting for the Michigna weather to warm up amd will pull the front mount distrutor and check it and replace the points and condensor. Will also do a compression check as I believe the compression was a little low last fall, but don't remember what it was. Am not looking at doing an engine rebuild as I would need ot take off the front loader and just don't use the tracotr that much. If it turns out to be a major repair I may just get rid of it. Not really able to do much on it in the current pole barn it's in as no heat and all of my tools aare in the other pole barn.
Open to any ideas and suggestions.
THanks,
Bill
 
Get someone to help you pull start it or pull it to the other pole barn where the heat and tools are and go to work on it.Pull the distributor and replace points/condenser with Echlin or Blue streak points #FD-6769X NAPA #CS35.Set points Condenser:NAPA #FA200
Standard Ignition #FD-71 .015 to get good spark
 
"Flathead" engines are cold-blooded by nature.

Rough choking when cold causes gas that's not atomized to drip out the airhorn drain.

The trick is to "finesse" the choke a bit so as much gasoline vapor as possible gets sucked up into the cylinders and lights off.
 
wsmm,Oh and if you have over choked it and flooded it replace the plugs as they are shorted with gas deposits or you can clean them with a propane torch to burn off deposits then clean wire brush and brake cleaner.Autolite 437 or NGK 3112.
 
"gas coming out of the intake". As below, sounds like over choking, BUT, it could also be an incorrectly set float or a sticky needle (crud). Even with over choking, fuel really shouldn't flow out. HTH
 
With the back blade and front loader on it is extremely hard to pull it to other barn or pull start it. Should have mentioned that in my original post, sorry.

Temperature up to 42 degree in the shade and 54 in the sun. Went out to the new pole barn, opened the fuel valve, set the throttle at 1/4 open,no choke, turned on the ignition and hit the start button. Turned over, but no start and no fuel leaking from the carburetor intake. Turned it off, let it sit about a minute, tried again same results. Pulled off the pre-air cleaner, on top of the air cleaner stack from the oil bath. Gave it a quick shot of starting fluid and hit the start button, turned over a couple of times and fired right up into a smooth idle. Let it idle for a minute or so, then increased the throttle and it was smooth running. Lifted the back blade and the front loader and drove it out of the pole barn. Parked it left it running while I repaired the climbing fence for my wife's grape plants, about 1/2 hour. Came back got on it and drove around the yard with no problem. Put it back in the pole barn shut it off and then restarted it with no problem Shut it down again and closed the fuel cock. I'm beginning to wonder if the tractor is just a real hard starter in the cold and the possibility that the summer gas that is in there just isn't volatile enough for the cold weather, especially with the tractor not being started enough. Hooked up the battery maintainer and called it a day. Will probably go out later and add some sea foam to the gas tank.
 

A long shot your fuel shut off is not shutting the fuel off... Turn the fuel off remove the fuel line at the carb is the fuel shut off... If NO the shut off is not closing all the way and the needle and seat is leaking enoufh fuel into the carb to flood it after a long sit...

Other than that have you checked spark with a spark tester...
 
I’ve owned my 2N for 2 winters now, it’s been very hard to start in the cold and I’ve learned a great deal about how to get it to start when it doesn’t want to.

I have to vary my technique based on temperature. Above 50 and I choke halfway and throttle about 1/3. In the 40’s full choke and 1/3 throttle. In the 30s and colder, I use a magnetic Katz heater that I plug in and stick to the intake manifold, then use the same 1/3 throttle and about 3/4 to full choke.

Summer it starts like a dream! Always runs good once it starts.has a little bit of blowby outthe oil fill if I take the cap off while running, but has plenty of power (for an N).
