  If the Ryobi Trimmer engine won't start, it could be due to no spark, no fuel, or a flooded engine. Try cleaning or replacing the spark plug and resetting the spark plug gap. Push the primer bulb until it's full of fuel. If it doesn't fill, a service dealer should be contacted because the primary fuel delivery system may be blocked. If the primer bulb fills, the engine may be flooded. Set the choke lever to the FULL CHOKE position, squeeze the trigger, and pull the rope repeatedly until the engine starts. Note that depending on the severity of the flooding, this may require numerous pulls of the rope.

  If your Ryobi Trimmer engine doesn't reach full speed and emits excessive smoke, the air filter might be dirty. You can try cleaning the air filter. Also, the spark plug may be fouled and need to be cleaned or replaced, and the spark plug gap reset. Contact a servicing dealer if the spark arrestor screen is dirty.

  If the Ryobi Trimmer engine emits too much smoke, there's probably too much oil in the crankcase. Drain the lubricant and refill it with the correct amount of 20W50 engine lubricant.

  If the line on your Ryobi Trimmer won't advance, it could be for several reasons: the line is welded to itself, there's not enough line on the spool, the line is worn too short, the line is tangled, or the engine speed is too slow. You can try replacing the line, installing more line, pulling the lines while alternately pressing down on and releasing the spool retainer, or removing the line from the spool and rewinding it. Also, make sure to advance the line at full throttle.

  If the Ryobi Trimmer engine starts, runs, and accelerates but won't idle, the idle speed screw on the carburetor likely needs adjustment. Turn the idle speed screw clockwise to increase the idle speed.

  If the Ryobi Trimmer engine rope cannot be pulled, it's likely that oil has entered the combustion chamber. This often happens when the unit is stored upside down for a long time. Remove and clean the spark plug. Drain the oil from the spark plug hole, then reinstall the spark plug. Before starting, check the engine lubricant and add more if needed.
