Good afternoon, how are you? I live in Brazil and I'm having problems with the D170 lawn mower, so I ask if you can make a video with the throttle springs, which keep the engine acceleration stable. thanks. 
I had a little over 60 hours on it when the belt broke. However, the belt only broke because one of the pulleys seized which caused the belt to break. Thanks for watching.
Thank you for this video! My belt just broke and this video will save me lots of time.
Those e170 do it quite often
Great video. Thanks so much for posting. It really helped.

how many hours did you have on the mower when you had to replace the belt?

I’ve had my mower for three years and I’ve replaced the belt every year.
Had about 80hrs on mine before the belt broke. Pulleys are fine tho
Missed the part when you put it on the motor pulley , guess just looped around motor pulley .
Not cotter pins
