</font><font color="blue" class="small">( I read somewhere on this site that the 1381 was for a gas engine and the 1626 was better suited for diesel. The 1626 is a bit bigger. Which I kinda like.
BTW. I use both WIX and NAPA. WIX makes filters for NAPA. I work for Dana who owns WIX filters and I used to work for NAPA. So, I can vouch for them both. Best filters on the market.)</font>
You read backwards. Check the application chart and you'll see ALL gasoline apps for one, some diesel for the other. Has something to do with the bypass valve. But it's academic if the 2 cyl uses diff filters than the 3 cyl.
Yes, WIX makes filters for NAPA - but to a lower standard than the ones they put their own name on. Despite the same pedigree, I'd use a WIX any day over a NAPA

I can be a bit hard headed at times, so bear with me. You got it running once - and it died. You subsequently confirmed fuel to one cylinder. So - IF THE GLOW PLUGS WORK - you should be able to get it started on at least one cylinder.
That said, hopefully that partial disassembly didn't throw a wrench in the works.

Well I know starting fluid is discouraged, but maybe you're trying to explode water. I've bit the bullet and used starting fluid in a few extreme cases. There's always some around, but for the most part I only use it to clean chain saws. But every once in a while it comes in handy to start a balky diesel.
I've avoided engine damage (first) by using it only when all else fails, and (second) spraying it very conservatively. I remove the air intake hose at the intake manifold, but I don't spray the starting fluid INTO the intake itself. With the hand throttle advanced at least half way, I turn the ignition with one hand and spray in the vicinity of the intake with the other. The natural aspiration of the intake stroke is usually enough to draw in a small amount of aerosol. Doesn't run long though, I have to apply a short spray when it threatens to die. But eventually the natural revolution of the engine finishes priming the fuel system, and pretty soon it's running on diesel fuel instead of starting fluid.
And if that doesn't do it, I'll back out gracefully and let you return to troubleshooting the injection system.

I believe those stories were likely about gasoline powered tractors

Yeah, thought so.
Greg_g, since I last posted, I've loosened the lines and pumped fuel all way up to the injectors by loosening the male couplings on top of the injection pump. Retightened the fittings and tractor still doesn't start. What's the chance there is an air bubble in the injection pump. It just doesn't make sense. I get fuel to and out of the pump and when I tighten everything back up, it looses it's prime. I'm at a loss.

I've taken out glow plugs, but never had cause to take out injectors on any of my five diesels yet (knock on wood). I know the new KAMA came with a lot of algae in the fuel tank. I didn't realize it till the sediment bowl was half full, but fortunately it didn't work its way any farther. Do you reckon you could have a pair of clogged injectors?
I had a mechanically injected Alfa Romeo (gasoline) that didn't tolerate the dirty Italian fuel very well. Injectors got clogged regularly. I cleaned them on the car, by spraying starting fluid into each tuned intake tube - one cylinder at a time. The violence of the explosions was enough to blast the crud off the injector tips for another few thousand miles.

One thing, Have you checked to make sure the FUEL cut off lever is not STUCK in the OFF postion? some come with cable that can get stuck, and mine has solid linkage, which can bind up if something is pulled overcenter ? just a thought, next thing to check it the lines loose and crank to see if INJUECTOR PUMP is spitting fuel, loosen same as before, the spring & needle I htink is to prevent the fuel form dripping back when off. but the injectorpump should push this off easy. if the injectorpump does not PUMP fuel (splat) out of the loose lines above it, then you maybe have a loose drive gear for the pump or a bad pump, this is easy step to check if it doesn't splat it out pretty good then the cutoff or pump drive or pump has some problems. you have eliminated the screens & lines so time to check the injector pump 7 drive mech, with cranking fuel out the line to injectors fittings. and if it does spit out there then the injectors are clogged. like i stated make sure that the fuel cut off level is hooked up right * not jammed ot OFF setting which is back twards the driver on the 3 cylinder not sure on 2 cyl.
