check the power in the battery before you start it, maybe your battery is draining? if your connecting it to another battery for it to start then its something electrical because you are then providing it with enough power to be able to start. in other words it couldnt be the carberator because the only thing the carb has would have that is electrical related is the choke, so sounds like somethings draining your batter. Try having it run and get the battery all charged up with it warm. then turn it off once the batter is charged and disconnect the battery and let it sit for as long as you would when it wont start. then try starting it while connecting the battery and if it starts right up then something is draining your battery.
How do you start it? Do you know how to start an engine or have you had this sort of trouble before on any engine that wasn't EFI & ran well & started Immediatly?
If you aren't setting a manual choke, is the automatic choke adjusted/setup & functioning OK? It's the biggest source of problem/s, then it's the owner.
Pump the throttle twice, take your foot off the pedal, that should give it more then enough fuel & set the fast idle cam now turn the key to the 'start' position cranking the engine, hold it there until the engine starts or 20 seconds have passed. If it coughed & sputtered &almost started but then continued to just crank, next time pump the throttle when that is happening.
No coughing sputtering any attempt at all to run with heavy fuel smell from the exhaust means it's flooded. Try again WITHOUT pumping the throttle but holding it down at least 1/2 way with only a Single push on it, no more crank until it starts..
Some engines have a little variation &need an individual touch that you've gotta experiment &learn.
