If it only pukes gas AFTER you crank it, likely the carb is FINE and you are overchoking it to compensate for another problem, such as weak spark.
EVERY old machine has it's peculiarities about starting.
As far as operating the choke, (once the engine is in operating condition) get the engine cranking, give the choke a quick "tug and release" and see if the engine "fires". Repeat if necessary.
Simply keeping the choke pulled out and continuing to crank the engine will flood ANY carburetor and make it puke gas out the air horn vent when you quit cranking it.
Some general advice...
When cranking a cold engine, the battery voltage is pulled down by the HEAVY demands of the starter and makes for a weak spark. The sparkplugs are likely wet with gasoline and the engine won't start 'til they are dried out or replaced.
If you are intending to regularly use this tractor, install an engine coolant heater and warm it up for a couple of hours before trying to start it.
Be SURE the battery is good and fully charged and the cables are good and heavy and all connections are CLEAN BRIGHT and TIGHT. A "float charger" will keep the battery fully charged and ready to go.
