Thanks Peter
But part of the symptoms were that I'd get the same effect when at prolonged
low RPM on paved roads. i.e. long traffic light or waiting in a Dunkin
Donuts line. Probably a sign to not eat donuts each workday morning :').
Fred Thomas suggested vapor lock due to the float bowl heating from the
tubular exhaust header. I have found an 8"x8" metal/asbestos plate attached
to the EGR pipe which goes from the engine compartment down under the
passenger side. I thought it was attached there by the previous owner to
protect the body. More likely it has slipped down and should be shielding
the carb from the header. I plan to move it up and see what happens.
Thanks
Winnie

Crap in the fuel tank is being churned up when you're driving on gravel
roads. Then it plugs up the fuel inlet pipe in the tank. Thats my guess.
