OK, so you've balanced your recip parts to .000000001 grams. Now, you go
fly. Fuel deposits (or carbon, or varnish, or oil accumulation on the bottom
of the piston, or ???) build up on the various parts until your balance is
reduced to, say, 1 gram. Was it worth all that aggravation?

Are you saying the answer to my original post is 1 gram? Or, just having
more fun?
I still haven't gotten what seems like a good answer, except for some very
good advice from Jim Baker. The book is on it way, Jim. Thanks for that
advice. I hate to bother Mattituck for their trade secrets. I'm sure every shop
has their limits which they don't want the world to know. Its even hard to
tell what Lycoming's limits are -- they just use letter codes to group the
weights. I can't find anything that defines these weights. That would help.
This is a take-your-time project, so I don't need an instant answer. I will
wait another day or two for listers to reply. BTW, I have gotten some good
advice in private emails. Most people who reply privately are very
knowledgeable and don't want to suffer all the criticism that an on list reply seems to
invite. I think its fun, too. Sorry, Archie, for getting a little excited
the other day. I'm sure you do very good work.

////////////////////////////////////////////////////////////////////////////////////////////////////////////////
I have been reading Archie's post for a few years now and I can assure ya he knows what he's saying and doing. I too get a "tire kicker" on my web site every few weeks that claim to be up to speed and after a few emails back and forth it is clear they have NEVER seen the inside of an engine, never less the finer details of tweaking one. My answer to you is get it as close to in balance as you feel is ok.
