hey Frank, I had the EXACT problem with my '85 and it drove me and a few
mechanics crazy.  It was the trottle switch, if that's waht it's
called...the thingy on top that revs the engine when you turn it by
hand...was lose.  A smart mechanic up here 'cleaned the trottle body and
rebushed it'.  Idle's as stable as a mountain now, never a surge since
after 10,000K. Hope it's that simple and good luck, Bruce
