Bike starts and idles with choke on. When you take choke off, it dies if you give it throttle? Am I reading your question right?

whether the timeing is right i'm not sure, but i did put new plug and battery in it. how is the timeing checked?
Supposed to see a good fat spark when viewed with the spark plug removed and held against the engine (ignition switched ON, tranmission in neutral, and using starter motor or kick starter to spin engine over, same as if attempting to crank it up, but with the plug removed).
Timing is best checked with a timing light while the engine is running, called "dynamic" timing as opposed to "static" timing with engine not running. Should also be able to watch the automatic timing advancer unit operate back and forth as rpm's are varied by blipping the throttle. Sometimes the advancer get sticky from lack of lubrication or need for cleaning.
Good Luck!

would it be better to kit the carb or buy a new or used
Am thinking wiredgeorge is likely correct about the pilot jet or pilot circuit still being obstructed. But carb replacement is usually not necessary. Sometimes replacing a really crusty inexpensive pilot jet is easier than cleaning it where the holes in it are easily damaged.
A too tight valve clearance can allow a cold engine to crank up and then cause the engine to die when it warms up. This is because the valves may be barely seating enough when cold and allowing sufficient compression for initial cranking. With insufficient clearance (gap), the expansion from heat no longer allows the valve to fully close against its seat, whereby the engine dies from loss of compression.
Many carbs have been wrongfully blamed when poor performance is actually due to poor compression or weak spark or improperly timed spark. Even a perfect carb cannot compensate for problems in these other components.
That's why it's a good idea to check the valve clearances and spark quality and ignition timing, including condition of points and point gap, before resorting to the carbs. Also air filter, ample clean fuel supply, and basically everything else, including fresh oil and filter, before resorting to the carbs.
Good Luck!

Fuel starvation may be caused by grit or crud inside the fuel tank collecting on and clogging the petcock tubes up inside the tank, dirty petcock screen, clogged petcock, dirty inline fuel filter, etc. Also possible fuel cap "vent" obstruction. And probably some other reasons not immediately comimg to mind.
Could remove and flush out fuel tank; remove, disassemble and clean petcock, replace in-line fuel filter; test run with fuel cap ajar (not snapped down tight) to test for clogged vent in cap.
Good Luck!
