No personal experience but would those saws with the elastostart be an option?OK guys. I'm 80 years old and did have a torn rotator cuff on my "pulling" side. The repair was not able to get all the muscles working properly so I'm in need of help with my Echo CS 490. It's a good saw and does everything I ask it to do - once it's started. So, is it possible to add a decompression valve to my saw? Or, would the cost of doing so outweigh the cost of selling this one and buying a different saw with a factory decomp valve? Many thanks, Ed
