I had the same model and always had a hard time getting it to start after taking it to shop it started three times ok then the hard to start all over again.

What is the correct spark plug gap for my STIHL trimmer, chainsaw or blower? The correct gap setting is 0.020″.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it.
If you`ve used the correct procedure to start your Stihl trimmer and it does not start, the problem is likely related to either the spark, the fuel or the air circulation in the combustion chamber. More often than not, it`s an easy fix, possibly involving replacement of a spark plug or air filter.
If your 2-stroke brushcutter fails to start, the simplest explanation is that there is not enough fuel: in this case you simply need to top it up. A 2-stroke brushcutter engine runs on fuel/oil mixture, which you can buy ready prepared, such as EFCO-Mix Alkilate alkylated mixture in a 5 L can.
A spark arrester is a mechanical device that traps or destroys hot exhaust particles expelled from an internal combustion engine.
Many spark plugs are tightened between 8-40nm (nanometer) and should be installed per the torque setting recommended by spark plug manufacturers. Moreover, it should also be done with a torque wrench (a particular socket wrench type) to avoid any over or under-tightening. But that isn`t all you need to know.
Worn clutch – Since the string trimmer clutch engages with one or more drive shafts attached to the trimmer head to rotate the head when the throttle trigger is depressed, a worn-out clutch may prevent the trimmer head from spinning. A new clutch assembly is relatively inexpensive and easy to install.
The clutch engages the clutch pads to spin the trimmer head. If the clutch assembly is defective, the clutch will not disengage the clutch pads, and the trimmer head will continue to spin, even at low speeds. If the clutch is defective, replace it.
A worn, dirty, oily, or improperly gapped spark plug can cause a weakThe job of the spark plug is to ignite the air/fuel mixture. A worn, dirty, oily, or improperly gapped spark plug can cause a weak spark, which can misfire or detonate and cause a loss of power.
Spark plugs are a key part of maintaining a petrol power tool, especially STIHL chainsaws, and you may think that one spark plug is much the same as another. A standard NGK spark plug and NGK spark plugs sold by STIHL may have the same part number stamped on them, but the STIHL NGK spark plug has some key differences.
SPARK PLUG GAP: 0.5 mm (0.020 in.)
The TS 350`s engine uses an electronic magneto ignition system with a single spark plug. Stihl supports the use of a Bosch WSR6F, Champion RCJ6Y or NGK BPMR7A spark plug with a 0.02-inch gap. The plug should have an M14 thread which is 0.37 inches long to fit the saw.
