Hi Jack,
Some more pictures of your lathe drive system would help.
How many steps do you have in the head-stock pulleys?
How is it being driven? (ie. how many pulley steps in your drive train?)
I suspect that maybe you have not found the back-gear mechanism?!?!?
From the manual I posted in post #19 of this thread:

(Sorry about the image sizes something wrong and it will not let me post full-size images!!!!)
(The second one is a "thumbnail view" that you should be able to click on to open bigger!)
It lists 6 direct speeds and 6 "back-gear" speeds.
Typically, it uses a shaft the site behind the headstock main shaft (thus the term "backgear").
You need to do two things to enable it:
- dis-engage a small lock on the headstock pulley that locks it to the headstock shaft
- move a lever that drives a cam that bring the gears on the back-gear shaft into mate with the headstock gears
I will try to locate some info for your specific lathe and post back with some pictures.
