<VV> Sucked Carb Screw

[Geoffrey Albert Clarke Johnson]

Have   a friends "64"  lakewood here that sucked a throttle plate brass 
screw today while driving.  Made a bad sound for a few then went away. 
Pulled the carb and put new brass screws in peened over (the one that was 
left had been out and not re-peened). Not my doing :-P
With the carb back on it sounds fine.
Anyway what do people think about this.   I have heard mention it will blow 
out.  Or it will dance in there and do bad stuff.
What do you guys think?  Drive it or pull the head?
Thanks
Geoff Johnson
