The 10,2 was fine. Will have to see about the 9,5

So the FS131 is a 4-mix? Stihl doesn't talk about that in the specs or owner's manual. Do you guys think this unit will hold up well for daily/weekly heavy grass trimming and light brush cutting, being used by crews that don't own the machine?

Definitely a 4-mix and it should hold up just fine. The valves will need adjusting when it gets hard to start or at about 130 hours.

Use fresh fuel and do the valve adjustment when it's needed it'll last for years. Also being four stroke it has good torque. If your not sure about it I would try one

well you can always use the fs 56,70,94 they are conventional 2 stroke.

the 240 is a conventional 2 stroke too

 

[DND 9000]

They are all (FS 56, 70,94) 2 stroke engines with stratified scavening technology (Stihl 2 Mix), also the FS 240.

 

[X 66 stang347 X]

FS91R-131 has 4 stroke internals.

If I was going to get a 4 stroke weedeater I would get a Honda. My stepdad has had one for about 15 years. He uses that thing hard and doesn't take care of it, yet it keeps on going.

4 stroke usually weigh noticably more than the 2 stroke .

 

[FergusonTO35]

Has Shindaiwa dropped the four strokes? I was on their website today and saw no mention of them.

 

[Nitehawk55]

I think all Shin are now rebranded Echo 2 stroke as are the saws .
