Question About Dinging Noise

Easy on me guys but why does some
of my weed eater make the dinging sound
sometime? Is it the octane? My echo,s do this
sometimes and the stilt is the worst.My equipment
runs great but does have some age on them.
I did a search and can not find anything.
Maybe it normal.

A couple/few years ago I switched from a lower end commercial RedMax to a commercial Stihl FS-80R 2-stroke. To my ear, the more powerful Stihl sounds cheap compared to my ultra-smooth revving/sounding RedMax I used for 8 years. I dig this Stihl 2-stroke a lot...the added power makes edging a breeze.

Stihl => I do hear some ping-y/ding-y sounds...but I run ethanol-free premium fuel so I'm pretty sure it's not pinging. Am more apt to chalk up these sounds as metallic/resonant noises that are completely normal.

Tery, you may want to check the clutch/drum. If the units have some age the clutch shoes may not be retracting completely when the rpms are lowered. The pivot points on the shoes get a bit sticky when exposed to drum dust on a continual basis. Check the bearings that support the drum--if they develop some wear, the condition may allow the drum to droop a bit thereby allowing the drum to bounce on the clutch. Just a couple of thoughts--your mileage may vary.

What is the model of the Echo trimmer?

Low RPM only, Really it does not affect the equipment s
ability to work other than the pinging sounds.
Thanks guys for the relpies. These engines have been worked hard
over the years .

Tery,

If the following link doesn't get you to the drum/clutch breakdown, go to www.echo-usa.com then click on support at top of page, then click on "parts catalogs", select your equipment, then go to the fan case clutch assembly. The breakdown will give you an idea of what I was talking about.

If you find the bearings noisy, replace them. As I recall the bearings are housed in plastic or aluminum, depending on age. If it happens to be plastic, worn bearings can get hot enough to melt/deform the plastic.

Before changing clutch & drum, you might try lowering the idle speed with the idle screw adjustment--this worked for a new Echo I had a few years ago. If the idle speed is too fast, the clutch is trying to engage, but doesn't quite get there.
