Pennzoil @ 32:1 ever since day 1!!!

In reply to TOM, I started the plane up last night after getting home (approx 3hrs. after shutting down at flying field) so it was totally cool, engine did the same thing after a few seconds so I know it is not a cooling issue, plus, the setup (cowl opening etc. prop.) has not changed since day one.

During the flight, I did some LONG verticals and the engine did not sag at all.....
