Sounds like a fuel problem for sure.
Possible that you mis-assembled the carb, or ended up creating an air leak somewhere?
It's not uncommon for a carb to plug a jet, just after a quick cleaning. When you clean a carb, you end up disturbing dirt & sediment. Unless you got it all out, it is free to plug things up. It's also possible that you disturbed sediment in the fuel line, and that made its way into the freshly cleaned carb.
