>Do you have an O2 sensor, and meter?
I have Tracy's air fuel gauge. Not sure quite how to interpret it yet.

Middle ideal.  Higher is richer, and lower is leaner.

I don't know. He's long gone. How would I find out?

Get a better gauge :-)

>get a better gauge
I did. An expensive westach quad. It reads 90psi before I start the engine. :(

You can buy better, but you can't pay more :-)

It has been totally cold after every short run.

It will be if your thermostat isn't opening.

I hope this is something internal to the engine. I never heard anything about an oil pressure regulator.

You have to pull the oil pan to get to it.  I wouldn't worry about it.  Higher pressure isn't bad, but it will waste just a little HP since we don't really need the higher pressure at our RPM range. 

Does everyone go through this, or is it just me? John

Just you (kidding)  :-)
