I know echos aren't exactly the favorite around here but I'm in the process of tuning a Echo CS-600P with a tach and need some guidance. Echos manuals show 12k-13k rpm is what it is to be tuned on the high side. Already yanked the limiting caps and richened it a bit over stock. Turning 12k right now on tach to be on the safe side for now.
I've had some hearing loss due to working around very large water cooled chillers in very tight mechanical rooms over the past few years. Even with hearing protection, plugs and muffs together, my ears ring for days..... So I am having a tough time hearing the saw 4 stroke when it's rich. I know this is going to make it difficult for tuning so I have a dti tech tach from amicks to help. Can anyone give me pretty good numbers for rpm's on these cs-600p's for it to be rich enough to 4 stroke wot and clean up when loaded up? I'd rather stay closer to rich than lean obviously which is why I left it at 12k wot out of wood but can't hear it 4 stroke at all..... even richened it up where it was turning 11k-11,200 and still couldn't hear it. Used a buddy's stihl MS361 to reference on sound, he swore it was 4 stroking, I couldn't hear it..... so I'm stuck with the tach and numbers unfortunately. Any help would be appreciated. Thanks!
