Thread: 066 Ignition module

Just a quick question for you seasoned Stihl guys pertaining to a stihl 066 ignition module. I am trying to replace assembly as saw starts and runs fine but at soon as it reaches 'operating temp' saw shuts down. (No spark condition) Let it cool and it will fire right back up. After removing module and anticipating pullling a part number off..to my surprise there is none. The only writing is 'Stihl" and 'IIDA' a 'C' on the side as well. Can anyone associate a part number with this module? I understand there are 3 variations on the theme for this module and would like to mail order to save some$$ but don't want to risk purchasing the wrong one. Any hints/help would be greatly appreciated.
I have located a few examples of the 'IIDA' but those seem to be on the smaller series saws... I would like to avoid matching it up at the local dealer as his prices can be a bit on the hefty side, however I do realize the purchasing two via mail order would be more expensive than one at the dealer. Thanks again.

Which flywheel do you have?

It appears after searching quite a few photos that I have 1122-400-1209flywheel. Hopefully the designs are different enough to pinpoint via other photos. Thanks again for any and all help.

There are 2 or 3 aluminum flywheels used on the 066. It has to do with where the key is indexed. Does your have one or two keyways cut in it?
