I just had my cylinders overhauled and now have 2 hrs on the engine. I
have been getting some mixed information about the proper break-in
procedure. Run "rich" or "lean"?. I am running 40 weight mineral oil.
Some say it is important to run hard and lean to prevent the walls from
glazing others say better to run rich to keep the engine cooler and
protect the valves. My engine oil temp is fine (175-180) and stable. I
don't have a cylinder head temp. I have had a little plug fouling and
one stack is dry black and the other stack is dry gray. I just replaced
a few plugs and hopefully that will fix the fouling problem.
Compression OK and mainly wanted to know about the "lean" or "rich'
issue. Maybe I'll also call Teledyne for the input. I'd appreciate any
thoughts on any of the above. Thanks..

hunt out the teledyne continental breakin information and use it. gets
rid of all the BS.
