Hello I was wondering if a missing pcv valve, pcv valve hose and intermotor preheat hose could cause symptoms that would make you believe the carburetor is not functioning properly. Thanks for your time.
Just a wild guess, but if the other end of the PCV hose is supposed to connect to the carb or the base of it, and the hose is missing, that might cause a vacuum leak.
There are are a lot of mechanics on this board, they are pretty good at helping. But you may want to mention what Jeep you have, the engine, and any information that might help define what you're working on.
The inter motor preheat hose provides warm air after startup to make it run a little better till it warms up the affect us marginal most have been removed without any issues.
The OCV system is a real player and should be fixed. It will have a direct impact in performance at all time. It uses vacuum to direct oil vapors to the intake to be burned. With that much of a vacuum issue it will not run cirrectly
