Stihl FS410C Engine struggling when I squeeze the throttle.

[Albasti]

Hi All,

I may be a little off topic here as I would like to ask a question about a Stihl FS410C strimmer I have an engine problem with, I saw some of you guys are pretty knowledgeable about Stihl products and engines so I thought I would try...

 

I have a Stihl FS410C strimmer that seems to start fine and ticks over very nicely but as soon as I squeeze the trigger to add power the engine seems to struggle and almost get choked to a point it sounds like it is going to die.

 

I'm not very good with engines but the fact that it ticks over well leads me to think it is a minor problem but wondered if anyone had any advice. I have a video on youtube of the issue if anyone is able to advise please: https://youtu.be/gWUIy_5_64E

 

Many Thanks for reading and any advice would be really appreciated and if you are local to London Oval can stand you a few pints or lunch if you can fix it.

Cheers

Alex

Sounds like the carb needs adjusting to me. I'd take it to local lawnmower repair place they should have it up and running in no time

Check the exhaust aint blocked , our Stihl blower was acting up and that's what it was .

Carb problem, adjust or clean, make sure fuel is fresh as well

Try running it without filter,we have had odd ones doing this they look spotless but are still choked up

Hi,

 

All I can add is check the exhaust nuts are tight as my FS85 ran a bit similar to how you describe with a loose exhaust.

 

The previous posts cover everything I would check.

To me that's the small filter in the carb itself doing that.
