[SEL] IHC mag/distributor question.

[Curt]

An employee brought in a HT,  IHC mag / distributor off of his IHC Cub 
this morning saying it no longer had fire. I've attached 4 photos and am 
looking for information as to how to troubleshoot it so I can repair it 
for him. And then instructions on how to re-time it on installation.

There are not a lot of numbers on it but the s/n says J4022924.
At the bottom is a small number on the casting 251493 R91

Facing the drive end it will turn and click counterclockwise, but I 
cannot turn it clockwise very far as it feels like it is up against a 
spring load.. What is the business direction? It behaves like a rotary 
imulse mag, but the electrical lead coming in the lower part of the case 
adds confusion.

Thanks for any assistance in identifying this and for information on it.
