I was wondering if someone familiar with this carb ( '84 Toyota 4x4 Aisan 2 Barrel ) could tell me what goes on the end of the OVCV shaft. Upon removal of the valve from the carb I found a bare shaft with groove in the end. logic tells me that a 4mm shaft moving back and forth in a about a 12mm hole will seal nothing, so there had to be a plunger or something. This is my first encounter with this particular animal and i'm stuck with the task of trying to fix something that someone else disassembled, made a mess of, and finally gave up on. And though i haven't been able to find any info to prove it (and i have spent pretty much an entire day looking) that there must be there must be a piece of the puzzle missing here. Am i wrong? Thanks in advance for taking the time to read this.
