Hi John,

Thanks...

Yes, could not turn over with the starter (it was engaging as I got some
prop movement).  Battery is probably culprit.

You are correct on temperature vs. oil pressure (typing too fast).

We had freezing temperature, but the hangar is insulated.  I did not observe
ice in the gascolator though.

It is a Stromberg and I have noticed the flat spot you describe.  I advanced
the throttle slowly the first time and then faster the second time... engine
died both times.

When I get the battery charged or replaced, I will give it all a try again.

Thanks for taking the time to reply, once again.

Best,
John
