I'v lost my manual for starting and maintaining my ryobi plt-2543y petrol strimmer

Hi! With the red know in one hand, push the spool down with th other to the female threaded shaft comes to the top. Then, hold the red know in the other hand with your index finger on the bolt in the middle, holding it down. Now start threading it onto the female shaft COUNTERCLOCKWISE! Once you get it, it get's easier. Good Luck!~Frank~

Check the spark plug and sheck the gap on it then check the wire

I also tried this.

1. Clean the carb wire gauze air filter behind the roto-choke knob. (undo the nut/washers & long bolt)
2. Deteremine if fuel is being fed to cylinder - Fully depress & prime the bulb about 7 times, turn to full choke. Pull start cord about 7 times. Remove spark plug see/smell fuel fumes/vapour present in cylinder
3. Determine if compression is weak - remove plug, put finger over plug port, pull start cord. Should be evident of resistance/pressure build up when cord is pulled.
4. Of course brand new plug!!! as above (I would try this first)

I had this problem twice in the past. I solved it the first time by replacingthe plug and setting the plug gap with a feeler guage. The next time it was a decoke of the cylinder (squirting through the plug hole) replacing the plug and leaving it overnight and then cleaning the air filter. It runs like a dream and has worked in Australia, Europe and the UK with no further problems. Also the fule mix has to be just right, I actually use 22:1 instead of 25:1 and do not use any petrol / gas with additives in (like Shell).
