YS 140 sport problem

[Bill Glaze]

I have no experience with the newer O.S., but the first O.S. engine I 
owned was a 1.08.  I liked it then, still do.  So much so that I bought 
a second one.  Interestingly, (to me anyhow) was that on the first 
engine, bearings lasted 350+ flights; on the second engine, they went 
out after 35 flights.  Go figure.
