Since it switches back to gas from deisel and runs good then, I'd tend to believe all the basic systems are functioning properly.
What would be the difference between cranking with the starter and switching to gas from deisel? Yep- RPM's. For some reason it's hard to get going when the engine is turning low(cranking) RPM's. Off the top of my head this could maybe be two things- One, there's a slight vacumn leak someplace that's not letting there be enough suction to pull gas through the carb at cranking speeds, but at higher RPM's(idling on deisel) there's enough to get things flowing. Second thing, and this is more of a guess than anything, it could be ignition related- does this have a mag or a distributor? If it's a mag, maybe it's not spinning fast enough at cranking speeds to build a good spark? Do these tractors, if they have mags, have an impulse coupling like the older F-series tractors did?
