There is very little that goes wrong with carburetors.---How is the motor running ?---Did you install a new water pump impeller last January ?-----What trouble shooting have you done if any?
The shift rod does NOT turn on these.----------There is no adjustment at the brass connecter either.----So are the notches on the shift rods both lined up with holes in the connecter.-----The only adjustment is at the shift lever.
Hopefully you installed a new water pump impeller.----If equipped with a plastic piece to open the throttle n, it might be broken.----I do not believe it is a fuel pump issue.
