HELP 44 2N won't start

[Barry In Indiana]

I have a 1944 2N. Saturday I put new points, condensor, rotor and new plug wires. After that it ran like sewing machine. Yesterday morning it started right up. Then about 1pm I went to start plowing the driveway and it wouldn"t start. it would cough a little but wouldn"t catch. I kept trying and ran the battery down. I put the charger on it and came in and waited. few ours later I went back out and same thing. I thought maybe something happened with the new parts I put on. I pulled each plug, cranked it over and each plug has a big fat blue spark. it acts like it flooded. I pulled the breather tube and gas will just pour out of the carb. I let it set over night and the same thing today. Any ideas?

in my limited experience, a flood of gas out the breather tube is a problem with the float setting. however, you didn't have problems earlier in the day.

are you sure your timing is correct? i have a side mount 8n so I don't know what can go wrong when you replace a front mount distributor, but it sounds like timing to me.

" I pulled the breather tube and gas will just pour out of the carb. I let it set over night and the same thing today. Any ideas?'

Yes.

Are you turning the gas off when you are done w/ the tractor for the day? And if you do & still have gas running out, then the sediment bowl valve is bad.

First, replace the plugs. If you flooded it, they're fouled & it will be it next to impossible to start. You don't need to toss them; heat the tips for a few seconds w/ a propane torch to burn off the invisible spark-robbing deposits from today's additive filled gasoline........or wash them in lacquer thinner.

The usual cause of gas dripping out of the carb throat is operator error. While each N has it's own starting sequence, none of them will start well by just yanking out the choke rod & holding it out for 5 or 10 seconds while the engine cranks. This is an updraft carb w/ a gravity fuel system; it is by it's very nature subject to flooding. Too much choke makes it happen.

Try this:

Key on, gas on 2 full turns, clutch in, 3/4 throttle, press the starter button. Let it crank for at least 3 - 4 seconds before you pull the choke rod. Then, don't hold it out for more than 2 or 3 seconds.

If you find out it will not start w/o excessive choking, you have problems.

As Bruce say are you turning off the gas when you park it?? If not you best check your oil before trying to run it it could well be over full and full of gas.
If you do shut it off then try this
Pull the air intake tube off and try to start it. If it starts then good chance you have a air cleaner that is full of ice due to this nice hot weather we are not having. Plus you plugs are likely to be gas fouled so heating them up may help also so as to clean off any gas fouling

I pulled the plugs and hit them all with the wire brush on my bench grinder and that didn't help. Could the float be sticking?

 

[old]

Yes the float could be sticking. Try this. Turn the gas off pull the carb drain plug and then turn the gas back on. Let it flow couple minutes. Catch it so as to look for water/dirt in it. Then turn the gas back off. put the drain plug back in then turn the gas on and count to 30. Turn the gas back off and try to start it. If ti starts quickly turn the gas on and give it a try

I always shut off the gas when I'm not running it. Yesterday when I pulled the plugs to check for spark I shot a squirt of starting fluid in each cylinder then put the plug back in and it still won't start. the only way I can even get a sputter out of it is to hand choke it and it will sputter but gas runs out of the carb.

You may have something clogging up the main jet in the carb then

No, it won't help. Not a bit.

That's why I said use a propane torch or lacquer thinner.

You been plowing snow right? Check rotor distributor for moisture.

' I pulled the plugs to check for spark I shot a squirt of starting fluid in each cylinder then put the plug back in and it still won't start."

All that did was clean the cylinder walls. The starting fluid evaporated by the time you got the plugs back in.

Remove the breather hose from the carb & spray the starting fluid in the carb throat while the engine is turning over.

Almost impossible to reinstall a front mount dist
out of time. You would have to break the tang on
the dist shaft.

Timing doesn't change by itself. Leave it alone.

(quoted from post at 22:29:36 01/06/14) Timing doesn't change by itself. Leave it alone.

So its impossible to mess up timing when replacing points etc eh? And with a front distributor it has to come off right? No i dont have one, but it was posibility to me.
