Gerry,
I went through this a couple of years ago with mine. You don't mention
the status of the radiator; was it cleaned out, rodded to make sure
there are no obstructions? Make sure the timing is correct. Retarded
timing could contribute to the problem. Also, on the XPAG engine there
are two small (3/16") holes in the water jacket that somehow help the
flow of the coolant through the engine that many times become clogged
and are overlooked in a rebuild. They are located behind the freeze
plugs under the carbs (you must remove the plugs to access them). This
was addressed many years ago in a tech article in TSO and is very
obscure information. Chip Old can most likely shed some more light on
this.
