Not a 97 expert, but if everything was running right, but it was jetted badly, surely the fuel consumption wouldn't be 3 or 4 times as bad as it should be. The ignition being a bit out or having no advance would not make it that bad either.

I'd be looking for fuel flowing past the needle valves and flooding the carbs. Something like that would vastly overfuel the motor, not having jets or acc pumps that are a couple of numbers off what they should be.
