Glenn,

The engine had this mag on it when I got it, it wasn't running when he gave it to me. I am fairly confident it is the correct mag.

So here is the latest. I got home tonight and checked a few things out. First of all, the manual I have been referencing covers the ACN and BKN but NOT the AKN I am working on. My blunder for assuming the information would be the same, this manual says the ACN and BKN should run with 17 deg advance. I checked the timing again, from my measurements its firing 36-37 degrees BTDC. So the first question I need to find the answer to is what is the correct angle for my spec number 67941? I will try to find a dealer to help me tomorrow. I don't find anything on the web.

To answer some of your questions. This does have the Zenith carb which I rebuilt. The impulse spring seems strong and I have a good spark when tripped. The engine runs quite well at idle. Watching time timing mark with a light it is rock solid without missing. Open the throttle a little and still a good smooth, solid running. I can hold the throttle over riding the governor and it runs fine... I think I just realized part of my problem. Must be something with governor or linkages....

I still believe its running with limited power. Would the timing be part of my problem?

Sorry this got some long.
