Gosh, you are right, cyberwolf! I went up on top of my house today to sweep off some straw and it was freezing up there! When I got back on the ground it was 90 degrees F again. Absolutely amazing. I majored in Aerospace Engineering way back in the 60's and all that temperature/altitude stuff hadn't been discovered yet, Thanks for the info!

Now, after all these decades of attempts I may be able to get an engine to run.

We can go back and forth here forever ,you break in your engines the way you like and i'll do the same.
The largest factor I have seen to the demise of any engine is the fact, the person that was useing it didnt have a clue as to how to set it up. On the bench or in a plane.
