As others have suggested, repairing the vacuum petcock is the correct route. A manual petcock is more often than not, a PITA and forgotten to either turn on OR turn off,. You go to start your bike and it it is sitting in a puddle of fuel with the possibility of >flame on< if anything sparks. It appears it was already mis-diagnosed as to being the cause of cutting out, when in fact the carbs were plugged from crap. The first thing to learn, is that the bike doesn't run very well on contaminated fuel.
If you rebuild the petcock with the proper parts, and polish the seat that the o-ring seals on it will work flawlessly for a long time. This goes without saying, the tank also needs to pe perfectly clean with fresh clean fuel in it. Doing these basic things saves on a LOT of guesswork.
it is usually best not to try to re-engineer things that teams of engineers already figured out for you.
