Blower Starter to Pulley Space

how much space is their suppose to be between the two jaws
of the blower starter and pulley

when screwing in blower starter jaw till it stops
how close/space should it be ?
mine is about a strong 1/8" of space, did not know if it should be closer

 

Ours is about 3/16" and when screwed all the way in, its bottomed out.

 

thats what i needed to know
when i screw mine in all the way i have a 1/8" space

 

space

just enough to clear the drive dogs after the engine starts and kick the starter back
