I have had this happen to me. It was
caused by a bad fuel pump. The pump would work fine around town but couldn’t
deliver enough gas for the highway. I ended up changing it out in a parking lot
in New Mexico while on vacation.

Subject: Re: IML: surging at
highway speed
Surging can be described several ways, gentle slow surges are usually
fuel issues, (lean) sudden bumps, or cut-outs are more likely to be electrical,
ignition, low voltage etc.Since the carbs of yesteryear, were jetted for
better fuel, re-jetting or smaller metering rods are due.Low fuel
pressure, restricted fuel filter, restiction in the tank pick-up, or possible
air leak on the suction side of the fuel line are also possible causes. An
ignition control unit usually gives, a go-no go kind of failure.One thing
you could try, to verify a lean issue, try closing the choke valve half way,
and road test again. This might richen the carb enough to reduce the
symptoms.That might head you in the right direction.Since all carter carbs
have the jets on the bottom of the float chamber, any trash in the carb will
give problems.Ya'll have a nice day, Dave.
