Either your guage is off or it is running a little hot. Does it
run cooler at lower temperatures? At no load it should be near the
thermostat temperature. If the radiator is sized correctly, the
heavy load should not run so hot, maybe 210-220. You gain nothing
by running so hot.
Sounds like it is time for a better cooling system. This could include
cleaning out the radiator, a better fan shroud, an electric booster
fan, or replacing the radiator with a higher capacity unit.
Assume your timing and advance are OK and you don't have a blown
head gasket. No amount of cooling will overcome either of these.
