Rebuilt 2N won't start

I recently completed my rebuild of my 43' 2N. I have replaced ALL of the electrical parts including points, condenser, coil, plugs, plug wires, resistor, starting plunger, wiring harness, etc. Also rebuilt the carb, made a new fuel line, and had the tank cleaned and coated. New tires, fluids, etc.

When I checked for spark at the plugs after the rebuild, I had good spark. There was good gas on the plugs and there was gas leaking out of the header/exhaust joint, so I know there was gas getting to the cylinders. Would'nt start....

I tried pulling it around the barnyard in 3rd gear. No luck. I then checked the plugs again and am not getting a spark. I don't know where to even start trouble shooting now...

Any suggestions are greatly appreciated!

If you haven"t found the problem, this is another suggestion, for others too. My 8n is a front mount distributor, and upon buying a new point / condenser set we realized that auto parts stores carry a different part set. Anyhow, with the new points and condenser in place we realized that the copper plate was not making contact from the points to the condenser. We solved this with some heavy gauge wire to bridge it. Would have never noticed this, but it was something that drove me crazy. Nonetheless, fired right back up. Make sure you get the exact set from somewhere, either here, or someplace like Davis Tractors. Good luck. I am now on to rewire the whole deal as well - can"t figure out the design of the steel wire loom, what a pain.

Sorry John, gotta fly out to Atlanta this week and won't be back till next week. You'll have to wait till next week to collect...or loose...the $$. I'll let you know what I find next weekend. Thank you all for suggestions.

Front mount distributors can be out of time. There is a timing screw on the left side of the distributor, real close to the clamp that holds the cap on. I do not suspect that, if you properly bench timed the distributor to the points. I would also point out that the distributor rotates counter clockwise and the firing order is 1-2-4-3. That means that plug wire 1 to distributor cap nipple 1, 2 to position 2 and 3 to position 3 and 4 to position 4. DO NOT reverse these. If you hold the distributor in your hand and turn it CCW, you will see that will create the correct firing order. You may want to check the voltage at the coil before you go any further...could be a simple switch issue.

Thanks guys...guess I'll have to pull off the hood and check those points again, as well as putting new plugs in. Darn!

Andy..... ...you do know that you don't haffta remove yer hood to do your frontmount distributor points, don't you? Ittza 2-bolt 15-minute finaggle to remove yer frontmount distributor and do the point on yer kitchen table. Just un-snapp yer 4-nipple cap and letter dangle. Then unbolt and remove. Replacement is a Reversal of the Removal ...except... just finger start yer 2-bolts and then twist yer rotor until it's OFFSET DRIVE TANGS drop into the camshaft drive groove. Don't haffta worry about timing 'cuz it can't gitt outta time. Then tighen'er up and re-snap yer crabcap. Simple, eh?..... ...Dell, yer self-appointed sparkie-meister

Andycapp..... ...(always wanted to do that, grin) Ya had sparkies and now you don't. Bettcha yer new points done went and slipped closed. The #8-32x3/16" points screw is notorious for slipping 'cuz it gitts invisable wear and just won't hold.

Check yer sparkie wires for correct firing order; 1,2,4,3,CCW. That means:
sparkie #1 is connected to nipple #1 at 10 o'clock
sparkie #2 is connected to nipple #2 at 8 o'clock
simple, eh? NOW PAY ATTENTION 'cuz it gitts tricky here
sparkie #4 is connected to nipple #3 at 4 o'clock
sparkie #3 is connected to nipple #4 at 2 o'clock
therefore fireing order is 1,2,4,3,CCW. isn't that amazing?

Make certain yer sparkies will jump a 3/16" gap. I use enny old sparkie and bend the side electrode out for a full 3/16" gap. Connect this "calibrated sparkie tester" to enny sparkie wire and ground to enny convenient real metal ground. (may haffta scrape some paint) Does yer sparkies jump the testergap with blue-snott authority?

Ya done went an flooded yer sparkies, modern no-lead gasoline leaves invisable wet deposits on the center insulator and the sparkies leak off to ground before the lazy sun-o-guns will jump the gap and sparkle. Change 'em to brand new DRY sparkies. AutoLite AL-437 is recommended. Always have a spare set of DRY CLEAN SPARKIES..... ....respectfully, Dell yer self-appointed sparkie-meister

John..... ....I wrote..... ."modern no-lead gasoline leaves invisable wet deposits on the center insulator and the sparkies leak off to ground before the lazy sun-o-guns will jump the gap and sparkle"

What do you propose to "clean" invisable deposits with? The "only clean" that works is HOT COMBUSTION to burn-off/dry the ceramic insulator. Sometime a "propane torch" will work but not well.

Actually, down here it has been ugly. Cold and then damp, warm fer a day, then cold, damp and ugly again. Right now, nice, partly coldy, 70n deg.

Up in PA, cold, dark, and pretty. Guess I'm just homesick.

I don't know 'bout sparkies, like you do. Someth'n 'bout invisible makes me jittery.

Once a year, though, I take dem sparkies out my "N" and clean 'em put 'em back in and she still runs good. Same sparkies fer the past 20 yrs. or so. Of course, she only gets 'bout 5 hrs work-out each year.

I wonder how she is doi'n up there in the shed?

Thanks,....John,PA

My lady has been so busy subbing. The teacher that is out has been diagnosed with brain tumors. So, I have been having to make my own activity. Got my paperwork done for 2004.

Not that complicated of electrical system. Sounds like youve been through it. Check for shorts, loose wires, points not working. Is ignition key on? You know that it will crank but not spark! I've been ther before in a not so proud moment!

Sounds like its flooded too. go light on the gas and pop the choke when cranking, just for a second, then again if need be.

good luck

You might consider checking the ignition switch.

Did you rebuild the distributor? I rebuilt mine and got spark for a very short while and then nothing. I had to go back in and redo the points again as moisture had gotten in there and started to corrode them (it had been a while since I rebuilt the distributor to when I actually got around to running the tractor). Front mount distributors hate water.

As others have said, get a set of AL-437 plugs. I had better luck with them than i did with the H-12's but I still have the new h-12s in my toolbox as spares. Flatheads flood REALLLY easy.

Lastly, check the spring that holds the throttle cable up by the radiator. Mine has a tendancy to want to arc jump from the copper plug wire end over to that spring and sometimes causes it to miss, especially at low idle. At least with a spark, i know i have...well...spark! I need to sinch it up closed with some pliers.

Gas on the plugs & leaking out of the manifold? That is not good; you've flooded it & fouled the plugs. Replace them & try again; do not pull the choke rod until the engine is turning, and then only for a second or two. Use AL-437 or Champion H-12 plugs.

I would suspect a timing problem. Not familiar with the 2N, but my NAA need to move the distributor ahead by one tooth before it wanted to start. You can start by finding TDC on #1 and setting the distributor to place the rotor before the #1 plug wire. Use the thumb test to find TDC on #1, but be aware that it'll blow your thumb off the hole before it reaches TDC, so allow for it by posotioning the rotor before the #1 plug. That got me big time on my rebuild.

The 2n has a front mount distributor so it cannot be
"a tooth off". It is driven by an offset tang and only
fits one way (without using a really big hammer).

I would look for slipped points, shorted points
or a stuck float valve in the carb.

Pull a spark plug boot and put in a new spark plug
and check for spark. Iffn you get a nice fat blue spark then i would suspect that it is flooded.

Turn off the gas and try to start her again -- do not use the choke.
