Hi, Are parts interchangeable between OS 46 SF and OS 46FX? Like piston/sleeve? Crank? Head? Carb? Backplate? I have a good running but crashed 46 FX and an old worn out 46 SF. Thought maybe I could get somethig working here. TIA, Dan.

OS engines' site has parts lists for both the 46SF and 46FX. Some parts are the same between them, some not.

Thanks for the reply. Doesn't look too promicing. Dan.
Probably the only major parts that would be interchangeable are the bearings. Both engines use the same bearings.
I did some experimenting a while back and no longer have the engines, but as I recall the 4D carb from a .46SF will drop into a .46FX. I seem to recall the .46SF backplate will also fit into the .46FX.
Cheers,
Bill
