Identifying West Bend Power Bee engines

[eric78]

I have an old West Bend engine, I believe it's a 580 or a 700, I can't find any markings that would tell me which it is, It is missing its fan shroud but is otherwise working, the only number I could find was #2703038 on the cast aluminium base pan where the fan shroud would go, I don't think this number though will identify the engine for me, where should I expect to find the number that will identify the engine?

I was looking to put a 700 on a bike of mine but was having trouble finding one. I called Power Products and talked to their outside sales rep. He couldn't help me but gave me a number to an old timer that build and raced them back in the day. This guy told me that even he could not tell the difference between a 580 and 700 without taking it apart to see what was inside.

According to a vintage kart website they had 5 digit serial numbers that started with 500, 580, 700 etc but I couldn't find it, I don't suppose I actually need to find out since the fan shroud I'm missing is apparently common to all three models anyway.

I have an older 2-stroke West Bend engine that I would like to identify.

I have been looking for a site that would help me ID it but haven't had any luck yet.

I would appreciate any links that might help.

Thanks
