I have a 211 with one and it just feels weird. That saw is too small to really benefit from it. However, I would love one for my 660. That thing will rip your arm off if it hits enough to pop up the decomp button when you aren't expecting it.Anyone have any experience with the Stihl ElastoStart, basically a normal starter with just the handle having the rope attached to the handle with a short bit of massive elastic bungy cord rubber material, to dampen shock and transfer energy. Thought of retrofitting those to my gear if practical. Any advice?
