-> bearings and discovered that the wrist pins had been fitted
-> wrong i.e. the piston pivots on the wrist pin instead of
-> the wrist pin in the rod. How can this be corrected?
At different times during the developement of the internal combustion
engine different theories have come into fashion.  MANY engines have the
wrist pin LOCKED to the rod, and DESIGNED to pivot in the piston.  I
don't remember anymore if the model A did but I can find out.  I'd find
something ELSE to worry about though.....   No faster than an "A"
turns it will never matter.
Look at it this way... pivoting in the piston you have TWO rather large
bearing surfaces to absorb the load versus ONE limited surface in the
rod end.
