    It seems the PO had some sort of vacuum issue. He disconnected and plugged the vacuum line to the petcock. Any idea why he would do that?

    Thanks for the help.

    Maybe the petcock has a ruptured diaphragm. So you've been running on "PRI" all this time; or has the petcock failed so completely it flows fuel no matter what position it's in?

    Not a good thing if one or more of your float valves fail...

    I had to call the how-to "Rebuilding the Yamaha Vacuum Fuel Valve" or somesuch nonsense because "petcock" wasn't allowed in a title without getting automatically censored.

    It's in "FAQ Suggestions."

    My kid calls 'em "Puppy Dicks." (Pet Cocks, get it?) Maybe I shoulda used that.

    I went "full PC" instead.

    Actually, it went like this:

    "I'm going out in the garage."

    "Whatcha doin', playing with doggy dongs again?"

    "Playing with WHAT???"

    "Puppy Dicks"

    "WHAAA???"

    "Pet Cocks, dad. Petcocks."
