Carb issue?

A pcv is cheap and can be changed over at any time with a varying sized orifices. You can also use a rubber hose with a designated orifice size without a pcv and run it from the air cleaner and its a cheap alternative. Replacing throttle plates is a PIA and costs money too so does epoxy. What happens if the epoxy comes out.....

Ideally you want all the air to come out the t-slot instead of introducing it into the airstream without fuel entrained in it.
Nah, replacing throttle blades is just nuts and bolts, like everything else. And epoxy done right does not fall out.
