Ohlsson Ohlsson & Rice: How to Tell Between 3/4 vs 1 hp Models

[CNew 403]

Hello,

    I’m still very new to O&R but learning a ton about these engines from all the great posts and enthusiasts on this forum. One thing I’m still a little puzzled by is how to distinguish between the 3/4 and 1 hp models when the decals are damaged or missing.  Are there any obvious tell-tale signs or clues that I can look for, or specific model/types?  

 

I hope his new thread lands in the right spot.  If I’ve goofed again, my apologies and I’ll need a little guidance as it seems I’m in the right Ohlsson section when adding a new thread.

 

Thanks!
