crankcase ventilation

yes, mine is very very similar. Already have a catch can collection for everything. old aluminum bottles. left front is the oil filler and closed. right back is open line into a catch can.
i did some day a connetion to the carb base. It worked well but when you turn off the engine the crank case wants air. it makes pfffffffffffff and sucks your carb empty. hahaha.

Guess i stick with what I have?
