Engine Operating Tips/Rich or Lean of Peak

[JAG]

JMH,

question #1: I noticed that you may have two different temperature scales for your cylinder temps. 190 Celsius is 374 Fahrenheit - which is a perfect temp for your cylinder heads. Continental recommends an optimal temperature of 380 degrees F for your cylinder heads.

On your note about item 9 - yes, I think this should be cylinder head temp and not oil.

Question #2: I am not a "by the numbers guy" as that. Read John Deacon's information online (pelican's Perch on Avweb, #63 through #66) to understand more about the combustion process. This is essential reading for anyone with an injected NA engine, especially our Skymasters.

Here is a table (Attached) that I developed from researching the requirements from Cessna and Continental for my 1966 Cessna 337A.
