Hello--
....Do TH gennys have the protective shut off of fuel when tank reaches 1/4 full... as do motorhomes? How would I know where/if this shut off valve exists on my TH?

All that is, is the bottom of the generator fuel pickup is physically higher in the tank than the MH engine fuel pickup. I agree with either the fuel filter (there's one on the carb of my generator, and another inline by the wheels...)
OR
the rubber fuel line may have cracks in it, allowing air to enter the system.
Take a small (1 gallon) can of fuel, and run a short fuel line from it to the carb (after disconnecting the existing line). Try and start the generator. If it runs, you've ruled out problems with the carb. Now it's a matter of isolating the problem(s).
