PCV issues?/hesitation
It is pretty simple. Whatever port (should be 3/8 hose) that the PCV and hose are attached to should be full manifold vacuum. You should be able to pull the PCV out of the valve cover and feel vacuum with your finger. If you remove the PCV from that end of the hose, the engine will not want to idle, and you should hear and feel a huge vacuum leak. Some carbs have a 3/8 port and some do not. I've never heard of a carb with a 3/8 hose fitting that is NOT full vacuum, unless someone plugged it or got the wrong base gasket, etc.
