[FC] Oil Cooler

[J R Read_HML]

I think that is an 80hp engine.  Don't know for certain.  If so, should not 
get THAT hot.  Were the heads ever de-flashed?  If you are not getting good 
air to all the fins, that could have a big impact on how hot the engine (and 
oil) eventually gets on a long run.
