How to start Ryobi Chainsaw if it won't start?

  If your Ryobi Chainsaw engine won't start, and you've ensured the ignition switch is in the start position, the issue could be a cracked or damaged spark plug. Replace it with a new one. If it still doesn't start, take it to a service dealer. Alternatively, the engine might be flooded. To fix this, turn off the ignition switch, remove the spark plug and boot, move the choke lever to the run position, and pull the starter cord 15 to 20 times to clear excess fuel. Clean and reinstall the spark plug. Set the ignition switch to run, push the primer bulb 10 times, and pull the starter three times with the choke lever at run. If it fails, move the choke lever to choke and repeat the normal starting procedure. If problems persist, try again with a new spark plug.

  If your Ryobi Chainsaw engine starts but won't accelerate properly, it might be due to the carburetor needing adjustment of the “L” (Low jet). In this case, it’s best to contact a service dealer for carburetor adjustment.

Why Ryobi Chainsaw engine does not reach full speed and/or emits excessive smoke?

  If your Ryobi Chainsaw engine does not reach full speed and/or emits excessive smoke, make sure you are using fresh fuel and the correct 2-stroke lubricant mix ratio. Another cause may be a dirty air filter. Clean the air filter. Also, the spark arrester screen might be dirty, so clean it. In some cases, the carburetor requires “H” (High jet) adjustment, so contact a service dealer.

  If your Ryobi Chainsaw bar and chain are running hot and smoking, the chain brake may be engaged. Disengage the chain brake. Alternatively, the chain tension might be too tight, so adjust the chain tension. Also, inspect the guide bar and chain for damage.

How to adjust Ryobi RCS5145N if it starts, runs, and accelerates but will not idle?

  Mary WoodAug 20, 2025
  If your Ryobi Chainsaw engine starts, runs, and accelerates but will not idle, the carburetor may require adjustment. To increase idling speed, turn the idling speed screw “T” clockwise. If the chain turns at idle, turn the idling speed screw “T” anticlockwise to decrease speed. Wear protective equipment and observe all safety instructions.
