Before you guys blast me, I know I screwed up. Don't know why I was successful on three carbs and I failed on one.
What did I do?
Several years ago, I removed (3 of the 4) mixture screw plugs in my '94. I was only partially successful on the 4th. Yeah, I now know the proper technique, but unfortunately I didn't go that route.
So, any ideas on getting out what's remaining of the 4th plug? There's about 1/4" of material left with about a half a millimeter less diameter than the bore of the screw gallery. Basically it's a 1/4" cylinder with an off-center bore in the bottom of the hole.
I've tried grabbing it with a coarse thread machine screw. I've half-heartedly attempted to "fold" the cylinder inward so I can grab it with a probe.
Neither worked, but I'm leary of putting too much pressure on it for fear of driving the screw into the seat.
