And by the way IMHO  a pump too far advanced helps to seat rings.
Hagar.

Seat rings? Did I read that correctly?  Hmmmmm at what setting far advanced
would be the best setting to help seat rings?  I can use that on mine. Mine
is set right at the max limit per the Bentley right now. 
mikitka.

Yes mikitka you did ----  BUT  I am not recommending doing it.  I was talking
about Gavrik Petersons  engine.

Lots of cylinder pressure help to seat rings.  A pump should NOT be too far
advanced -- it will bring cylinder pressure up to a point where it harms the engine.
So put a good load on the engine instead. And use Mineralube.  ---NO additives.

Gavrik is an aggressive driver (not like me) so his rings may be ok.  A good
leak-down record will tell.

If blowby is high ---then the compression rings are not ok ---- if they are ok then
the oil scraper rings are in trouble . ---He is using oil.

But my feeling about Gavriks engine is that ---- it will be ok --he is a perfectionist
so  ---first he must ask the machinist for numbers like  cylinder to piston gap and
ring gaps.  And cylinder finish. And type of rings ? chromed or not ?.

Loren  --- you have the piston to cylinder gap handy  --please post it --and while you
are at it tell Jeff Rakus where to get a tap for headbolt threads.

In closing ---DO not adjust pump to seat rings.

Hagar.
