My 2N with 6v system,good points,new plugs,after running a month ago will not start.Fuel is good,however it is not firing.Pulled distributor,checked breaker gap at .18, checked continuity, O.K. . Continuity in coil good. New, good battery,turns over fine,not that cold,60 degrees plus today. Where do I go from here.

Bench tested coil,Dist,rotor, etc, good blue spark to each wire point at the cap. When put back on the 2N,there is no fire to the plugs which are new Autolites. Resistor block replaced,new harness replaced two months ago.Will crank great,new battery. I am stumped!. I know it has to be something easy that has been overlooked. Engine internals good,full overhaul less than 18 months. 6 volt original, ignition switch is good, starter rebuilt. As always, thanks Gentlemen.

The plug gap spec is .025-.028 (I keep mine at .030, cause it runs better like that)

.014-.016 is the gap for exhaust valves.

You need to isolate it down a little better twixt a fuel or or sparkie problem. ( this is assuming no mechanical problem exists to the internals of the engine that would cause a compression problem)

Pull one of plugs out and let it rest in the hole where you will be able to see it fire... turn the key on and crank her over while you watch for sparks. If you have good spark it will probably be a fuel problem.

if you get you a can of starting fluid and spray it in the carb and if it fires .. you probably have a fuel problem.

Fuel delivery problems are most likely plugged up filters or a carb that needs cleaning.

If you have no sparkies you need to trace down that down to the voltage to the points , coil or distrubtor problems.

let us know how you make out

Thank you for the comments gentlemen,will check for fire at the plugs,etc.. and isolate back from there. From the 9n 2n newsletter shop talk article,they showed a gap range from .15 to .18,so I will check again after church manana.
Sprayed starting fluid into the carb,carb is clean,still would not fire. Something tells me it is the ol'connection between the coil and the cap. But hey, it's been in the family since 42' so I'll keep it.

I would not worry over .001 either way. If you have a test light or a voltmeter you can check to see that voltage is getting to your points and they are opening and closing as the engine rotates. If so you probably have a probalem on the High Voltage side of things.

Ya cant get rid of the thing if its been in the family that long.. besides it's just now getting broke in good.

I believe the gap is suppose to be .017, did you check for spark at the plugs?
