It has been my expreience that this(JAMAC) is the only place that you will receive any clear information about your Kemore machine. After a long, frustrating period of time, I found a number of which I could contact JAMAC. I usually use extension #14, though you might be able to find a better one.
If you're looking for a guide(or guides in this case) to thread colors and their names and part numbers, go to these helpful links.
