Does the carb have a high speed needle or fixed main jet? If it has a needle how is it currently set? Have you warmed the tractor and adjusted this new carb? Did the tractor come to you with the original carb? I assume the carb you bought is same as the one that came with the tractor when you bought it. Is it the correct carb for the tractor? I'm asking because I'm wondering if the carb is jetted correctly internal. I would be especially suspicious if it were a fixed jet carb. You've checked the compression and you say it starts and runs OK at idle. The timing is still a question in my mind even though you say it is timed I am not there to check it myself. This is mechanical advance only? No vac advance? How did you set timing? Did you use a timing light? Or did you do it static with a test light at the points? I would go all thru the ignition once again in terms of check points gap and timing. The timing spec is usually given with no advance. If you timed it with a light with engine running you want a very low speed to insure no advance is coming in from the mechanical advance. If you are using a timing light you should be able to see the advance come in if you watch the light and pick up the rpm. We've got to know the timing is really spot on and steady and the advance comes in as it should. You say pull the choke out and it runs. How far are you pulling the choke? Just a little? all the way?
Something is amiss here because if I read your list of things done and believe in fact they are done correctly, the motor should be running and it's not.
