Idle speed screw reset on a stihl br 350

SOURCE: starts ok wont pick up speed

check to see if the throttle cable is hooked up to the carb. look at the back of the motor and watch as you pull the the throttle to see if the cable is hooked up. if the cable looks to be working correctly then pull the spark plug up and heat it up with a blow torch and put it back in. if the motor runs good then you need a new spark plug. if those two things do not work then you need to replace the carb diapram and gaskets.

SOURCE: Stihl weedeater starts but won't run at high speed

This sounds like a timing problem.
It is too far retarded, and needs advancing a couple of thou.
There you go:)

SOURCE: my stihl fs 350 wont start at all any sugestions

I would have a shop do a compression test on the engine. It should be at least 100 psi to run. And then a spark test on the ignition module to see if it firing to the spark plug. I would look at a carburetor rebuild. I would also mix up some fresh fuel mixture; anything over 30 days now is considered bad gas.

Flooded? Try a new plug, or get that one cleaned up. If it is sparking and wet, it should fire, even if it doesn't run, it should spark. Did you put the jets or the needle valves back to where they were? I think they start out at 1 1/4 turns out , then adjust the low and high. If it is fouling out with too much gas, the low speed jet is open too far.
