I think you said you have a nonstock carb so I'm not going to be able to help I haven't messed with the after market carbs.
I reread some of the posts and I'm wondering is the float level set too low it runs fine for a little while then starts stumbling?! Or you might have a float needle sticking and starving it for fuel. There should also be a vent on the carb. On thechina carbs the opening for the vent is under the aircleaner right by the pivot arm for the choke I haven't run into one being plugged yet but it could cause a fuel issue if it happened to get plugged. If you still have the stock carb try it and see if the fuel problem goes away.
Yes I do get the fuel leak at the cap, it is a stock carb and the vent for the carb sometimes will spit fuel out there.... I to thought about the float bowl level, byut wasnt sure on adjusting it so I didnt mees with the arms yet. In case you missed it I swapped the stock jet out for a Delortto #68.
