Hello Doktor Tim and fellow listers;

I am concerned that I have a twin in the Northwest:  Owns both a 912 and a
Vanagon.  If the good doktor tells me that there is a 914 and a Mercedes
in the stable too, I will truly begin to worry.....

As for balancing:  ALWAYS balance the engine when rebuilding;  It makes an
unbelievable difference in the overall smoothness and performance of the
engine.  The engine's response to minor adjustments (idle, timing, valves)
is much more pronounced, therefore easier.  Everything stays in adjustment
longer, everything stays tight longer.  You may, however, suddenly notice
all kinds of new noises from other components now that your engine is so
quiet.

A good machine shop can balance the engine at the same time they are
performing the tasks normally associated with a rebuild. They will balance
everything that moves (including clutch plate, flywheel, pulleys) and mark
them so that  you do not corrupt the balance during the assembly process.

Regards to all,
Jon Kanas
