Strimmer dies without any throttle?

Brontosaurus

I'm not experienced with strimmers, but mine dies if I don't give it throttle, so I have to give it shorts bursts of throttle to keep it going when not cutting anything.

I'm probably being an eejit or missing someting?

Presume it's petrol? Try adjusting the idle screw

The idle screw is one poss as mentioned. With the strimmer off operate the trigger and follow down to the mechanism on the strimmer engine which the trigger operates. You'll see a screw that that mechanism comes to rest against when the trigger is released. You can adjust the screw in/out to increase/ reduce the idle speed.

Chances are though that your not turning off the choke once you've started the strimmer. There will be settings for cold and hot starts. The choke, if left on once the engine has gotten a bit warm will cause the engine to die when the trigger is released.

Thanks lads, yeah the choke is off, I'll try adjusting the screw

Have you got the 2-stroke mx right?

Is it new or an older machine that might have been left and gotten gunky inside?

I’m assuming most strimmers ( all of mine do ) normally deactivate the choke when applying the throttle so that wouldn’t be an issue.

Take the air filter off and see what it does.

Honda petrol strimmers do not. You must set the choke manually, so auto choke is not universal.

Yes, but Hondas are four stroke which would probably explain that.

FYI mine only dis-engages the choke when you fully press the throttle
