M37 Hesitation

[G744]

Loss of vacuum when accelerating makes the plunger go down.

It is done that way as it is all related to operating the governor.

You are correct the piston works against a spring. When you hit the throttle there is a sudden drop in vacuum and the spring pushes the piston in the opposite direction and pumps fuel into the carburetor. Figure 03-1 in the M-37 ORD 9 is a good exploded view of the carb.
