Well I guess it's gonna get a .91 then,either os or magnum I can't get a good deal on saito[&o] just hope I don't have to add weight to the tail.
I've owned both the OS and Magnum...I got rid of the OS due to valve spring issues...Never bought another OS 4 stroke since...
To be fair this was awhile ago, about 7 years or so...If I had a need I may buy another OS 4-Stroke as I haven't heard of this problem in a while...
On the other hand, my wife's 60 size trainer has a Magnum 91 in it since 2005. It was 4 years old then (bought in 2000 or 2001). Runs very reliably year in and year out...
