Tecumseh Diaphragm Carb

[Rivets]

I been asked to get a Jiffy Ice Drill ready for ice fishing season. Has a Tecumseh engine model AV520-670-104A. I’ve got the engine running, but for the life of me I can’t find governed top speed or idle speeds for this engine. Everything tells me to look on microfiche card #40, but as most of you know that this technology most of us don’t have any more. It’s not even in my old 2-cycle 1979 Technicians Handbook. Hoping someone who works on these old engines has it. Thank you in advance. Rivets.

Top governor speed 4500 rpm

Thank you. Can you tell me where you found it, I’d like to print it out and add it to my 3-ring binder of obscure things to know.
