Ys 45fs ?
 

Just looking for some info on this engine
thinking between this one and the OS61
I know about there 4strokes but not about the 2stroke
any info would help in my decision.

Thanks
John

john, the ys will bury most 45-50 sport engines and will hold it's own against the jett 45. it is also as strong as many a 60 but probably not a new os. it is also a joy to set up and run.

Aha!
 

I will chime in once again as a huge YS-45 fan-

This is one of the better and most powerful sport engines you can possess- Just a half-click below the Jett stuff :eek:

Built in pump and tons of power-

My YS .45fs is about the most reliable, user friendly engine I have! I use an OS #8 plug changed out every year and never have a problem. Blown some fuel tank seals though! Great engines with tons of power.
