Is this complete air cooled OS Speed engine with lower unit without the carb?

No, it is a car engine, OS XZ-B Spec III that will be converted to fit an OS XM lower. (lower not included) Carb is included, but it is the stock car carb that comes with OS 21 XZ-B Spec III engine.

Ok thanks for the clarification and the information

For those who may not know, O.S. Is the undisputed dominant engine manufacturer in the car scene. These are very strong engines, and I believe the same series that Rody Roem’s VS series is based off of.
Considering the unknowns surrounding Novarossi at the moment, this would be a great power plant to get ahead of the curve. These engines sold new at amain hobbies for $500, so you are getting a fully converted motor for cheaper than getting a new one and doing it yourself. Great deal Joern!

Hey Joern,

What is is the crank size for this engine, 14mm or 14.5mm? Also, just to confirm, this is the engine correct?

It is a 14 mm crank.
This is the actual box, see part number for your reference.
