It is not so much the operating temperature, but the wide range of 
operating temperatures that occur between idle, coast, cruise, 
acceleration, etc for an engine that is, for all practical purposes, 
"warmed up."  This necessitates rather loose tolerances--by design--to 
account for thermal expansion of the various parts.

Beyond making adjustments to the carburetor jetting, you might consider 
installing a universal fit catalytic converter in the exhaust system.
