Broke a clutch spring on my Stihl 029 Super (039 engine). While tracking down replacement parts I figured to go ahead and replace the clutch sprocket while I was in there. It is grooved a little bit. My saw has a 8 tooth sprocket but I see 7 tooth but not 8s available. Stihl says both will work as long as the pitch is the same.
It’s my understanding that going to the 7 will reduce chain speed but increase low end torque. Is that desirable? Is there any other reason to not use the 7?
