OK.  Here is Cessna Service Letter 21 dated 9/19/46

Subject: Method of adjusting Starter Control

The object of this adjustment is to make sure that the satrter  gears are 
fully engaged before electrical contact is made, to prevent breakage of 
starter gear teeth.

1. Turn "OFF" all switches
2. Engage starter gear by pushing with thumb on gear shaft and rotating 
propellor slowly until shaft moves into crankcase. (Engaged Position)
3. Hold the shaft in the engaged position and pull back on starter lever 
until the bottom point just touches the starter gear shaft, but does not 
compress inner springs in the starter shaft.
4. Adjust the bolt on the starter arm so that the switch button is
depressed 
completely.  The locknut may have to be moved to the other side of the arm
to 
obtain this adjustment.  [See my note below]
5.  Check for 1/16" clearance between [the bottom point] of the starter
lever 
and gear shaft when the arm is fully released.

Notes:
On point 4 above:  Adjust the bolt so that the switch is just pressed far 
enough to make contact.  You want to ensure that the starter gear is fully

engaged BEFORE power is applied.  The inner springs in the gear shaft will

allow that final pull to close the circuit.

Make sure the return spring is installed on the starter arm and that it is

sufficent to pull the arm back and create the 1/16" clearance.

Also from Cessna: "Continental Motors advise us that if this adjustment is

right, it is impossible to chew up the gears on the starter or the gear in

the engine. Let's go with them on that, and see that all our airplanes are

adjusted right"
