Is it true that the manual for th 46fx has the wrong breakin procedure the 10 sec 4cycle 10 sec 2 cycle thing?Does this shorten the life of the engine?

For the fuels used in North America, you should use these instructions :

The factory-supplied instrucions won't hurt the enginne much, but are more suited for the fuels used in Japan, which have different types of oils, we are told.

Hello,

I've just discovered OS Fx series are ABN (no longer ABC as with OS SF / FSR series). What's the point ? Is it better ? I doubt it seriously as I continuously see piston/liner troubles with these engines. Is something better planned at OS engines corp ? Back to ABC piston/liners perhaps ? Sad story...

Thanks

Won't hurt much?how much? Sad comment that break in instructions are not correct.
