Angus, an access panel may work be better. That plug is sealed for a reason called leaking which can cause a big boom
. I don't even like the adj jet for that very reason, a possible drip.
In 34 years I never removed the plug to check the gas as I would of checked it at the separator as it would accumulate there first.
Any fuel problems need to be addressed at the tank first and then work to the carb.
If draining the carb helps for a bit it is not fixed only catastrophe postponed
.
