I do not have a FS-80.

I do have four FS55R weed whackers. One was originally a standard FS-55 and two were always FS-55R's and one was originally a FS-45 curved shaft weed whacker. All four are the 27.2cc #4140 two stroke power head.

Two of these have Straight shafts, gear heads and guards from FS-90 four strokes and two have their original FS-55R straight flex shafts, gear heads, and guards. All four look like FS-55R's

The FS-90 solid steel shaft units have a heavier feel than the flex shaft versions. This is partially due to the fact that the solid steel shaft FS-90 is 6" longer than the FS-55 straight flex shaft. The flex shaft itself weighs less than the solid steel shaft for the flex wound wire shaft is hollow. Operationally for me one works as well as the other and I have never had any trouble with the flex type shafts.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .
