Stihl 661 vs 088 - Video

Filmed in April, 2021
A little bit of a wardrobe malfunction with the old roller nose bar with the big mount Stihl - 14mm studs - mating up with the 661. Clearly I had not tried the "new & improved" Cannon bar spacer before hand. I had conjured up my own when runnin' the 72" bar on another 661 with the unlimited coil & adjustable carb.
The 088 is seen in the start rope compression test doing quite well. It is far from clapped out...
The 661 has a few tanks run through it. It probably has not turned the corner - not broken in yet.
The 661 had, and it was by far, the worst of it in this session. I used props and talked about the knot section here.
088 has a 60mm bore x 43mm stroke. 121.58cc in displacement.
661 has a 56mm bore x 37mm stroke. 91.13cc in displacement.
The 661 gives up ~ 30.45cc of displacement.
088 factory hp rated at 8.6. 661 factory rated at 7.1 to 7.2 depending upon where you look.
The 661 is giving up at least 1.4 hp stock for stock.
Looking at the timed runs -
088 at 11,640 went 29.83 dwn, 29.17 up, & 30.60 dwn in the more solid wood
661cm-r at 13,140 max went 30.86 down and 32.50 up.
In the end, the 661 held it's own while AT THE SAME TIME had more of the knot component.
I'm super well pleased at the performance of the 661.
