I bought a SRM-210 a few months ago and I've got a couple complaints with it. First off, the thing is hard to start requiring 8 or so pulls of the rope before it starts and yes I prime it. When it does attempt to fire up it then takes a while to warm up so that it will run right. It's pretty much been this way since it was new. I'm about to put a new spark plug in it and hopefully that will help it out a little. Once it's warmed up it will easily fire right up on the first pull but, if you let it cool off for a very few minutes it'll require a few more cranks and possibly require the use of the choke to get it running again. The other thing that I don't like is the head itself. The head that came on the 210 I bought was supposed to be the better head but, if that's Echo's idea of a superior head then I sure don't want to see their cheaper head. The string already stretched out the holes that are supposed to hold the string and then I started bending the string in the middle and sliding the center down into the slots of the head to hold them instead. The string often hangs and doesn't want to feed properly. I much prefer the Husqvarna head on my 323L over this echo head. Maybe I should put a Husqvarna head on this Echo. I bought a Husqvarna head a while back and it came with other sized parts in the pack to make it work with other trimmers so hopefully it will work on an Echo. Unless someone has an alternative suggestion. I'm hoping that the local Echo dealer can adjust the carb on the 210 to help it start more easily and I'll figure the head out eventually possibly with the help of someone on here. Thanks much in advance. PS. If I had noticed that the 210 didn't have carb adjustment screws that can be easily adjusted I probably wouldn't have bought it.
