^^ could be multiple problems, start with one. Can you keep it running above can idol... after it starts? There is no set idol turns and some carbs need the boss( the one you tapped) filed down, to let the screw go in deeper in order to get it to idol high enough. If you can keep it running by throttle id screw idol all the way in & try that 1st, if not: do a search, to make sure your slides and bowls are in/on correct carb. And make sure you put choke tube back in. Also make sure exhaust isn't clogged ...with a rat... nest Sent from my SM-A505U using Tapatalk
