Couple of questions...

The 4Kw in my 230 has two timing marks on the back shroud. One is TDC
and one is 21° BTDC. When I install the Pertonix sensor I figured to
set the timing at 21° but the manuals I've seen say 20° or 25°.

Question: Would there be any point in changing the timing? To what?

I've seen reference to that but don't remember anyone posting timing
numbers. Advancing the timing as far as possible is a good thing in a
car. More advance be good for an Onan?

I've torn the Barbarian down quite a ways. Starter is off (bracket is
in good shape) and I removed the Oil Filter adaptor. Both bolts were
pretty loose. I think that's where my oil leak was coming from.

Question: I see "copper" washers under a number of bolts and nuts. No
lock washers. What's the deal with those? Are they some form of lock
washer? Are they there to avoid electrolysis between aluminum castings
and steel hardware?

I'm adding lock washers and Blue Loctite, just because...

TIA,
Kelvin
