Me again.
Having resolved many of the issues discussed in previous posts (many thanks to the helpful postees of ATC), it has come to pass that my carb is giving me trouble.
The truck, as a reminder, is an 86 1/2 ton, with a 350 from a 79 3/4 ton driving it. It seems that the choke coil is intermittently engaging the choke. I'm told that short of a rebuild, it's not possible to fix this. I am of modest skills mechanically, certainly unable to confirm the diagnosis. Is it possible to fix it (ie: myself), where would I get parts? My interest lies in obtaining the carb that will offer me the best efficiency. Should I be looking at a M4Me or M4Mc? What's the difference? (I know that one has a heat-actuated choke and one has an electrical choke) What's the difference in performance?
Is there an aftermarket carb that anyone can recommend for fuel economy that can beat a factory carb? I'm not interested in tearing up the strip.
