<VV> 140 Running hot ??? Help

[FrankCB at aol.com]

Michael,
    How do you know it's running "very hot"?  When  my Corsa 180 was being 
driven almost daily, at highway cruising it normally  ran 400 deg.F on the stock 
(uncalibrated) CHT gauge.  Under full throttle  up a long hill showing 8 to 
10 psi boost it would go to 450 deg.F.  But to  my mind this was not 
excessively hot.
    If you don't have a restriction in the cooling air  flow through the 
engine, then overheating could be due to running too lean  (vacuum leaks??) or 
running retarded on your ignition timing.
    Let us know what you find.

Hi gang.  My 140 is running very hot. The carbs are rebuilt. Timing and 
points are  set. Fuel pressure is correct. Belt is not slipping and both 
cooling vents  open correctly. When I drive it and pull over or slow down to 
let it get  cool, it won't. It is running a little rich. ?????? Thanks  
Michael
