Crankshaft balance

OK. They managed to get things in balance - within one gram.
The only thing was the starter gear with the torsional damper. Because
of the fluid damper it changes - about 5g out max. Does anybody know if

5g is acceptable for a 10" flywheel?

One gram is darn close for your application. You will notice a
difference when ya fire up the new beast. As for the damper, if it is a
fluid style i can tell you they never repeat while spinning up on a
balancer machine. Temp differences cause the viscious fluid to migrate
differently every time so don't sweat the small numbers there. I am
curiuos, Was this engine a first time run motor and never been into
before? You would think with all the FAA requirments they would dictate
part weights in a new "certified" motor to be closer then 5-8 grams.
I also want to say Jim was very good at reading into the fine print and
giving a great feel of what was trying to be said. I am a little
forward in expressing my views and do sometimes rub people the wrong
way and hope we can get over this feud.

Happy Hollidays all you guys.

The machine shop found the biggest discrepancy in couple of rod big
ends - 10g?.

Was this engine a first time run motor and never been into before?...

I got this engine in pieces with 1500 loged hours and rebuilt it. I
put about 85hrs on it since then. But the vib got annoying above
2400rpm. Here in SD its not ideal flying weather till Feb. so I decided
to use the time to improve the engine.
