John Deere Model A spluttering

Note about the throttle linkage to the govenor: The linkage needs to be “1/2 a hole short”, i.e. when the throttle is wide open, engine stopped, take the linkage out of the arm on the carb. The gov. spring should pull the linkage 1/2 of the hole dia. past the point where it will go in. There are no springs inside the gov. housing, about all that can happen in there is a thrown weight or the sleeve stuck from sitting.
