 Yeah, I was disappointed.  During the warm-up laps, my Mc91B was running great, then suddenly went weird.  I thought, hmmm, this is how it runs when the carb nuts come loose.  Well, I was 50% right.  One of the BDC studs had snapped... below flush.

I'll try to extract the stump with a left-handed drill bit... wish me luck.  If that fails I'll need a manifold.

Later in the day, my son Alex's Mc91 BDC manifold cracked too!  Oh well.

If anyone has a couple of surplus Mc91x BDC manifolds to sell, please send me a PM.
