Default Best way to keep a string trimmer cool?
I was over at my grandmother-in-law's place today doing some weed trimming. It's a fairly large lot with lots of trees and fences to trim around. After about an hour of solid work, I shut off the trimmer to change the line. Went to crank it back up and it would idle but shut off when I gave it the throttle. After I let it sit for a good 30 minutes, it worked fine again. So I assume it overheated?

This doesn't seem to be just this particular trimmer, as I had a different one the last time I did this at her property. Except that trimmer overheated after only 30 minutes of runtime.

Is there a good way to keep these things cool? Or is it just the consumer grade equipment isn't meant for long sessions, and I should get a commercial grade unit?

Echo is the same brand my local repair shop advertises as well. Maybe once my Cub Cadet trimmer dies (which I got for free btw), I might look into a professional grade trimmer.

ECHO makes a premium product in Lake Zurich, IL. And, they have a 5 year consumer warranty.

Sounds like vapor lock. Carburetor gets hot when shut down because there is no fuel and air flow to cool off. Try idling a moment before hitting kill. If that doesn't work, consider richen the mixture a little to run cooler.

I'll try the idle trick. This trimmer calls for 40:1 ratio, which is what I've been using in it (the premix canned stuff).

Have a look at how much oil is in a 40 to 1 mix and you expect that to provide good lubrication and cooling , I have been using 25 to 1 mix with no problems also no smoke as the motor is pretty much always running at peak RPM
Some will de-cry my usage but the advice came from some one who makes a living working on small engines , not a hobbyist

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
