[SEL] Orings

[Harry Terpstra]

Curt,
I think I run it about 3 days a year (20 hours) a year.
I use the cheap rings from about $3.00 each.
I have to add that this engine runs very light (no drag) and stays very cool 
and it coasts for a long time.
IMO it's worth a try on any engine with blowby.

Harry
