Hang in there fella... had my 9N go through similar problems when I got it, and then assembling it after I tore it down and apart for a restoration. It blew my mind and my patience. It can totaly fry a sane man's senses when it just won't start. Best thing to do is walk away from it, clear your head, and go at it with renewed drive (no pun intended). consider everyone else's replies but here is my approach to the same problem (in case you havent't done this yet). Look at each potential problem area and break it down into three parts.
1. Electrical/ignition
2. Gas and fuel
3. Mechanical r.e. sticking valves, oil pumps, pistons, rings, air filter replace oil in that, ensure no mouse nests in engine, exhaust, etc. etc.
a. Systematically problem solve the electrical until you have the correct voltage at the coil and a strong blue spark at the plugs. Just doing that, and spending the time only on the elctrical installation by installing new wires if old ones are brittl, frayed, rotted etc, timing it, new points and correct gap, condensor, rotor, plugs, switches (if old or suspect), checking all connections looking tight and clean, fully charged battery. Run through the checklist and be thorough. This will give some peace of mind. Follow the current flow from the switch to the coil and to the plugs with a light meter and volt meter. Every component of your electrical system should be in top notch shape. Remove the distributor and ensure that wires are grounded correctly and not touching and shorting out. TDC, Rotor at 1. Once done, check the spark and volts if you have a meter and if it is all up to snuff...good...walk away and revisit the tractor another day to do the fuel part of the problem. 2. Carburetor/Fuel. Start at the tank and ensure fuel flow from the tank to the carb is great. Old gas? any debris in the tank settling in to the line? Check throttle, linkages, spray em down. Remove carb and overhaul it if it has not been done. A cheap and semi routine easy to do simple maintenance thing. Follow the manual...set the float, blow out the jets, replace all needle valves, soak it in a heavy duty solvent for a day or two, rebuild it, reassemble on to tractor. Check fuel flow into carb and out the bottom through drain. Check linkages at governor to carb... If you are certain that the fuel flow is good, plugs are wet, move on to step three... Valves. Can't offer you any advice there, but while you have the carb off, remove the muffler, remove inspection plates and give them a look over and fire away the questions to Dell, Zane, and others here...sounds like if you have done the ignition and fuel part of this as thorough and complete as possible you're moving closer to the problem. Sorry for the long reply...but if you are like me, I sometimes tend to jumble up the no start dillemma and bounce around until I approach it with a logical system and sequence. 9N'er
