It is going to die when you remove the PCV hose, that is perfectly normal. When you remove the hose with the engine running, you just created a major vacuum leak, one so large the engine management system can not compensate for it, and it kills the engine. When you removed the hose, you probably noticed a very loud sucking sound, that was engine vacuum. It is not going to run with that large of a vacuum leak. To check the PCV valve, remove it from the valve cover and shake it, close to your ear and listen to it. If you hear a rattling sound the one way valve inside is loose and not stuck in the valve, so the PCV valve will operate normally. If you shake the PCV valve and do not hear a rattling sound, it is bad and should be replaced. Blowby around the carb, such as oil residue is normal if you have an older engine. This is from oil residue from the crankcase gases being recirculated through the PCV system, that is it's job. To remove gases from the crankcase, which is full of oil. A little oily substance around the carb area is perfectly normal.

PCV= Positive Crankcase Ventilation.........not huge Vacuum
leak....of course the engine is going to die....
Blow by is in the engine cylinder when exhaust gases are forced
past the rings causing Blow-by this may be picked up by the
PCV and will deposit in the Air cleaner.....if it is really blow by
then changing the carb would be a waste of money and would not address the problem you are having.....Good luck!

i own a repair shop,,and if it dies when you take it off you need to replace it,,you may also want to look for other hoses that may be cracked or closing together on it,,it should still idle when the pcv valve is out of the engine,,but check it after you replace it with a new one,,it should be fine,,good luck with it,i hope this help,s.

Change the PCV valve and leave the carburetor alone.
