Cheetah 42 cc engine

Have anybody got info on a Cheeta 42 (2 stroke) petrol engine? I've got a new one (in the box but could be a few years old) but the manual is not clear what % the oil content should be. This engine is made in the USA.
Anybody knows this engine?

It is the same as a US41 except it has electronic ignition if I remember correctly

18 X 10 prop and 32:1 straight mineral oil with standard grade pump gasoline witll be fine.

They turn around 7300 with the 18 X 10 prop after they've been run at leaswt an hour break-in.

Thanks W8YE, is this Cheetah (US41) an engine worth keeping or not? - I don't know it at all.
All my other engines are Zenoah's.

I've been around a lot of US 41 and Quadra 42 iengines. They were very popular before the chinese engines appeared.

While not a 3D type engine, they make a fine sport engine that will last you many years.

Your engine dates back to around the year 2000
