I have a newer Echo string trimmer 210 or 2100 cant remember which one it is, but when I trim for about 20 min. the motor cover gets so hot you cant touch it. My other ones that are older dont have that problem. Any ideas??

You do realize that Echo specifies 89 octane? Although, like you, I just use the 87. I don't seem to have that problem though. The motor housing gets warm, but not so hot you can't even touch it.

Same deal here, I use the SRM-210 and 87 octane. It gets warm, most brands would I think, but not hot enough that you couldn't touch it.

Maybe try some 89 octane and see what happens.

i run 91 octane in all my 2 stroke stuff. i think they run better and i know they run cooler. the cost is not that much i use about four gal of mixed gas a week and it only costs 15 cents more a gal. thats 60 cents extra a week. its worth it to me to keep my equipment in good shape. i have an echo gt2400 that is 9 yrs old and still starts on two pulls. im shure it has lated longer with the 91 octane.

I have been using 87 for years and never had a problem. I have 4 of the same trimmers and this is the only one that it is doing it. It is almost to hot to touch. When you lean your arm on it you know it.

Use 89 octane in my echo trimmers and they get very hot. I strapped glove to the top of it wear my arm touchs it. This works great and feels good.

I have the 210i, and I know that it gets hot, but I don't think that it gets too hot to touch. I knbow someone posted on here a few weeks ago about the same prob, might wanna do a search on it.

BTW, I run 87 in mine, but its been somewhat hard to start, does the 89 help with this?

87 octane and amsoil 80:1. Works great, no smoke, no carbon buildup, no problems.

One of the best small engine (2-cycle) mechanics around here told me to run 93 octane in all my 2-stroke stuff if I wanted it to go the distance. I also put sta-bil in all my gas regardless of how long I intend to keep it. I've had gas go bad in as little as two weeks. I also run Amsoil @ 80:1.
