JD,
I really think it is a fuel supply related issue. I think the carb filter might be the problem, but the valve right before the carb (return to tank/carb T valve) might be getting weak. Do you know where I can get a new valve? I havent been able to find a replacement.
JOhn
John, the fitting before the carb that has the fuel return line to the tank is merely a "Tee" with no moving parts, just an orifice for the bled-off fuel to return to the tank.
John, I have the same year and model chassis under my Class C. First, have you replaced the little Engine Stopper filter in the carburetor inlet? I added a clear plastic inline filter in the feed line from the select valve to the carb, right at the select valve. Used a loop of fuel line to keep from having to cut and bend the steel fuel lines. Line diameter was 5/16". Then I replaced the little ceramic filter in the carb inlet. Mine has a feed-to-carb-to- return tee right at the carb, so remember, any blockage in the carb inlet filter will just send the fuel back to the tank. NOW, at about the speed you describe, on a hot day, with a/c running, after I'd been shut down half an hour to go eat, the engine stuttered, missed, and shut down. I ended up replacing my ignition coil. No problems since. A friend tipped me that the ignition "brain" (aluminum box on driver side fender liner) can also cause problems in these trucks. I actually bought both parts at Autozone and changed only the coil. Thinking I'll get a second coil to be able to carry new spares for both. Cost of both was well under $30 total and there were "lifetime warranties" on at least the module, maybe coil too. Camp happy and God Bless, jd |
