On these four cylinder engines with symetrical crankshafts, the crankshaft
can be balanced by itself with nothing else attached, and the pistons and
con-rods are generally matched in weight within 1/2 gram during a balancing
job. The flywheel is not counterbalanced but has a constant cylindrical
cross section (same shape all around) and is typically balanced alone, not
while attached to the crankshaft. Therefore, rotating the flywheel will
not unbalance the engine.
