How Do You Start A Stihl Weedeater FS55r?

If you have any issues, here’s a start and troubleshooting guide to get your trimmer head into action.

First, remove the starter cover to inspect the flywheel, crankshaft, and the Woodruf key alignment.

If this is okay, you can move on.

Is your starter handle hard to pull?

  • Remove the starter cover. Can your starter work smoothly? If yes, reattach the cover and move on to step 2. If not, the answer is to repair your starter.
  1. Is your trimmer equipped with a decompression valve? If it is, you can proceed, although if not, move to step 3.
  • Leave your ignition off, set the valve then pull your starter loop handle.
  • Pull carefully to release the valve. Can you feel a difference in the effort required?

If yes, continue with step 3; if not, you’ll need to repair or replace your Stihl FS 55 decompression valve.

  1. Was your trimmer operated in a lean state, where there could be metal transfer from the engine’s piston to its cylinder wall?

If it was, it could cause a leaky intake in the engine connection, carb; crankcase seals, cracked fuel delivery lines, all from running on gas with no 2-cycle oil.

  • Disconnect your spark plug wire and remove your plug.
  • Remove the muffler to clean and also the spark arrestor before reinstalling.
  • Shine a light into the plug hole to check the cylinder via the exhaust port. It should have a smooth surface, yet if it’s damaged, it could look dull with spots or smears.

Pull your starter carefully to inspect your rising and falling piston.

If you saw any spots or scratches on your cylinder, the trimmer was operated in a lean condition. Finding a quality repair for a Stihl FS 55 trimmer with engine damage is often higher than the cost of a new Stihl FS 55 trimmer.

It would take an engine breakdown, rebore the cylinder, and assembly with larger piston and piston rings, etc. Doing this at home isn’t possible because of the tools required.

Trying to run your trimmer without a repair would lead to a lack of performance and creating lots of smoke as the oil burns when it leaks down the edges of the pistons. (Learn How To Get Rid Of Goat Head Stickers In Your Yard)
