Bruce --

I can't tell you how many of those things I ruined on my Spitfire as 
I reassembled it and tried to figure out how the whole thing worked.
I now carry a spare (well, I did when I actually drove the Spit!). 
I'd recommend you carry one, as well.

Yes, having a slit in it will cause rough idling, as well as poor 
performance at speed (might run OK without a load, but don't drive it 
too far!).

PB Blaster is the best thing I can think of for the allen screw.

1957 TR3, TS15098L, now with an O!  Undergoing frame-off restoration
begun 9/99.  Currently awaiting warm weather and funds.

1977 Spitfire, FM64159U, with an O.  In need of a comprehensive
restoration (again); will probably become a Spit6 or a Spit8.
