I got the bug to take my 91 XII for its first spin in about six months... but it got cut way short by the discovery of a leaking #4 carb bowl gasket.

So, I'm about to order up some bowl gaskets and some JIS screw bits to get er done... found out when going through the carbs on my 454 LTD (same carbs) that a phillips bit doesn't work so great on the bowl screws.
Question, has anyone attempted to reseal the bowls without pulling the carb rack? If I can sneak the bowls out with a 90 degree bit driver, that's how I'll do it.
