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.
