Roger, anything is possible - this Yanny had been rode hard and put away wet before I paid too much for it. Unfortunately it is about 4 hours away, and it will be another week or so before I get to go play with it again. I've looked at some of the throttle pix in this thread, so I will see if anything has been removed from that region (also, I couldn't locate a thermostart bowl, so I don't think I have that either).
