The vent should not be plugged it is meant to breath so that pressure will not build up in the crankcase. I don't think it would affect the idle but it would definitely not be good to run high rpm like that. That being said, you may need to adjust the a/f mix screw. best way is to adjust the idle speed to where it will run (around 1000 rpms is good) and adjust in or out 1/4 turn at a time, giving 15 seconds for adjustment to take affect.While adjusting you want the rpms to rise with each adjustment not go down. If adjustments cause rpms to lower then adjust screw the other way. Keep adjusting until the rpms are at highest point. From there a 1/2 turn in either direction should cause rpms to drop. This how you know you are in the right spot. Then adjust your idle speed where you want it.
