Still trying to get this tractor to hit to my best guess I still think its a timing issue. Set timing mark at 8 degrees on flywheel . Then inserted distributor into hole. With enough finagling everything popped in the place with rotor pointing maybe just a little past number one cylinder. Then placed cap on rotated distributor back and forth with #1 plug grounded when plug fired I stopped. Does this appear to be a good starting point.
Then a side note ,rotated motor back a fuss were rotor was dead nuts pointing at #1 clearly rite to it. Looked at Flywheel marks through the peep hole. It was at 28 degrees.
Thanks for your input
 
Sounds good IF the #1 is up on compression stroke.

If you didn't check that, pull the #1 plug, hold your finger over the hole,
hand turn the engine until you feel compression, keep turning to the timing
mark. Then see if the rotor is pointing to #1.

If it's pointing to #4, pull the distributor out and turn it to #1 position.
 
Yes on the compression stroke ,double checked many times what I did since by my self . Raised rear tire 4th gear put a little piece of tissue over #1 when it blew off finished turning front Pulley by hand to dial in
 
So you referenced turning motor over then on the compression stroke with a rotor pointing at number one then checking the timing mark in a perfect world what degree should that be.
Thanks
 
I wouldn't trust a tissue. Even with the exhaust valve open 'some' air will
still come out the plug hole.

Might be something to recheck.
 
sometimes the lobes that the points rub on,turns when should not. take the dist. out take the
plate out(the one the points bolt to). under there is a advance device that comes loose and
will cause all those symptions you are having. hope this helps.
 
Or reposition the plug wires with number one where the rotor is pointing in correct order and correct rotation
 
Yes rolled Motor over with finger on number one could feel the compression stroke then set fly wheel at 8 and inserted the distributor so leading edge of rotor was it number one. Then put plug wire into number one marked on the cap with the spark plug grounded and when the spark plug sparked backed it off just a little bit. Still no start not even attempt to even fire some thing seems like its 180 off. Even spring starting fluid into the carb nothing
 
Here is something I ran into on a 2 cylinder Deere. I know I am comparing apples to oranges but I will still tell the story. The intake valve in one cylinder was eroded by mouse pee so it did not seal. When that cylinder came up on compression the leaky valve allowed compression to blow back into the carburetor. This pulse messed up the fuel mixture in the carb so the next cylinder did not fire at cranking speeds. In a previous post you mentioned low compression in the middle two cylinders. Could compression blowing by where it should not be somehow messing up the carb? I very highly doubt if this is your problem, like one in a million but I thought I would throw it out there anyway.
 
Going on week six I am at a total loss. My next to do is to pull the valve cover off and see what the valves are doing.These four cylinders weather be by Allis Chalmers 45, or an old Ford 3600 diesel which is a 3 cylinder are so simple.
