Been looking for a good deal on a Stihl for a couple of weeks now...no luck. This Echo CS-400 popped up on our local 'For Sale' site and I jumped on it after reading some good reviews on here. The saw idles but cuts out when you give it a little throttle. I'm hoping it's just a carb adjustment or bad gas or something similar. So, where do I start? I've been reading on the Muffler Mod and carb adjustment...but being a chainsaw newbie, I think I may just want to get it back to factory good before messing with it any. Besides draining the gas and changing the plug, is there anything I can do to get it going? Also, what's a good chain to purchase for casual use. We have 1 acre currently with a few hardwoods, but we're currently building a house on our new 8.5 acre purchase. The saw will only be used a handful of times a year for a mixture of hardwoods and pine trees. So, I need a good all around chain for general purpose I guess. Oh yeah, it's an 18-inch bar. Thanks everyone! Looking forward to modding it a little after I get it running correctly.
