LS,

I discuss this on my Pipistrel project web site.  Here's a link to the Firewall
Forward page <http://www.pipistrelbuilders.com/firewall_forward.html>.
Scroll down the page to the entries for
Dec 5, 2010, Dec 18th, 2010 and Jan 2nd, 2011.  I found that the partially
open position of the thermostat when cold wasn't enough to get all the lines
full of oil, and you definitely want to get all the air out of them.

I would check the lifters as well, although they may remain full of oil.
The problem is that you will be turning the prop through a number of
revolutions before the system is full of oil again, so the oil may be
squeezed out of the lifters, at least to some degree.  Follow the procedure
described in the Rotax 912 Installation Manual, section 31.11 (available in
the Documentation
area<http://www.rotax-aircraft-engines.com/desktopdefault.aspx/tabid-49>of
the Rotax web site).  It will be easy to see of the lifters need to be
re-primed.  There is also a video of the priming procedure available
on the Rotax
Owners site <http://joomla.rotax-owner.com/>.  If you don't already have a
subscription to this site, I recommend it for an excellent information
resource (in addition to this forum).

Regards,
