First I would try doing an actual comp. test on it, sometimes it may feel like there is enough comp. but thers really not if that checks ok make sure your spark is a good strong blue spark sometimes you can have spark but the coil could be going bad and not generating a stong enough spark. another thing it could be in you pilot jetting, How was the plug burning? your pilot jetting is what controls your idle to 1/4 throttle so that might be another place to look.

After cranking the engine is the spark plug wet or dry?..If its wet you are either flooded or the spark plug is not firing under pressure...If its dry you are not getting fuel into the engine regardless of whether it's reaching the carb from the tank..Could be your choke isn't working or possibly some broken reeds(unlikely) bad seals etc..I would try a little gas into the cylinder and see if it fires up and go from there.
