Bad PCV? Idle issue

Replaced the PCV and fuel filter just for insurance. I also ordered a new fuel pressure gauge.

Took the carb to my engine builder and he blew it all out and said it looked good with one exception, the base plate was loose. He took the screws out of it with the tips of his fingers. Put them back in and re-torqued with Loctite.

I'm taking it to a cruise-in tonight. We shall see....
