Well, I am going to get my first four stroke engine and I have a few questions. I am going to put the four stroke in my 4*60 arf. I have only used two strokes so far, about 6 years or so. Right now I have the O.S.61 in it, but I think I need the sound of the four stroke now. I have use a few differant two strokes engines in the past from differant companys and I have found the O.S. if the best in my mind because they just run great with no problems. Question #1, is this the same with the O.S. four strokes.
I am looking at the four stroke O.S. FS-91 II Surpass and/or the O.S. FS-70II. With only a $40.00 price differance between the two I am ASSUMING I should go with the FS-91. Question #2, is this right.
Also I am going to ask about the Magnum XL-91 RFS, priced at $150 that sounds real good to me. I am just wondering if the Magnum will run as good as the O.S. I have never had a magnum engine so I don not know anything about them. I guess I am asking if any of you have both Magnums and O.S four stroke and if so which you like the best or are they the same. Thanks.
