I've had this engine apart and rebuilt it and I don't remember a gap in the output shaft to suggest that this is a collar. I'll have a closer look today.

As to the colours, I know that they are not correct, but I've never liked painted engines and the mower looks good as it is. Each to his own, I guess. Lucky there are no concours events for mowers smile
