Stihl HS45 Trimmer Acting up

[matthew horner]

Well, basically, I pulled it out the other day and it is running funny. It will start and idle, but as soon as I go no choke it acts like it is sick, and forget full throttle, it just shuts off.
Spark plug is clean, fresh gas, clean air filter, and I took the carb off and cleaned it etc.
I looked for a high speed adjustment on the carb but found nothing, just one screw that seemed to affect the idle only.
Any ideas on this?
Thanks,
Matthew

Replace the carburetor. We have the same problem sometimes with ours. Cheaper to replace new than rebuild.

Check exhaust port for carbon buildup, block muffler?? Not likely but don't hurt. Do that before you pay a penny.

Good luck

Good Idea! I will check that out.
I'm getting to sell the hedgers so I need them running well.
