    Thank you Jim. Yes, I need some tips ! I've removed the carb and the plate holding the diaphram but don't know how to approach the jet.However, I found the fuel pipe had deteriorated and was leaking so I question whether the problem could be the carb getting too much air. I welcome your response.

The carburetor needs to be disassembled and cleaned with carb. cleaner. Or, it needs a new carburetor kit. If you need tips on how to do this, just let me know.

    If by fuel pipe you mean fuel line, yes, this could cause the problem your having. The jet that you referred to is more than likely the needle valve that sets under the diaphragm.
    So, go ahead and replace the fuel lines and make sure that you get the correct sizes for both. One may be smaller than the other, depending on the size of the trimmer. (TIP: Before feeding the fuel lines into tank, cut the lines at an angle, making it easier to insert into gas tank holes. Once you have them where you want them, cut square.)
    One fuel line goes from the carb. to the bottom of the tank, with the fuel filter attached at the end inside tank. This line should rest comfortably on the bottom of tank.
    The other line goes from the primer bulb to just inside the gas tank, (about 1/2 to 1 inch), with coupling attached to the end.
    If this doesn't solve the problem, and I believe it will, let me know. And when you respond to this comment, try to respond through the comment button. For some reason, I didn't get an e-mail from your comment. I just happened to stumble on it when going over my solutions.

    Thanks for the rating Mike. If you should have any questions about "Drywall Finishing/Patching, or know someone who does, put your questions to Category:Tools- Building & Power- Hand Tools" at Fixya.com

RYOBI 2 stroke strimmer starting on choke but not running off choke


First is to control gaskets (best way to do that is carefully tighten the 4 nuts slightly from the cylinder and the 2 of the carburetor somewhat because of possible gasket leaking to control second thing remove the exhaust(muffler) look the piston that its smooth (no grooves on the surface of the piston or the springs to see ) if all was ok until now you have luck, next step is carburetor clean and service it fuelhoses not leaking or primer bulb tankfilter tankairiation. i think first is that its having loose some compression by a too poor fuel mixture but more on a to bad L ( in most case +H was having a too lean adjustment ) or there was working with full trottle too long in a row without intermediate break, the most problems on this kind of saws leaking primerbulb tankairiation problems ( fuel canals special on models with a zama carburetor)

Starting up Ryobi Petrol Strimmer


full choke on , push petrol bubble 5 times then pull starter cord., with luck it will kick in to life after a 20/30 secs put on half choke , run again for 30 secs the no ckoke.

The main problem with Ryobi products is that they flood very very easly. So the more time you try and pump petrol into the carb the more it will flood . If that happenes then choke off and switch off and then just pull starter cord for about 30 secs then switch on and it could start if not prime it again as above good luck

Can't start the strimmer. It is a petrol strimmer, Partner Colibri. Is there a technique other than pulling the cord? Does it need more than just petrol? would be pleased if you could help. Regards...


Start procedure, switch the ignition switch on, press the primer bulb as many times as it takes to 3/4 fill the bulb, put the choke to the full position,hold the throttle trigger open, crank the engine until it fires once, move the choke to the centre position, crank the engine until it fires up and runs, once warm move the choke to the open position.

Ryobi CS30 Trimmer starts and runs in full choke and half choke but stumbles and stalls on run. Not up to full rpms when in full choke and half choke....


You probably need a slight carburetor adjustment. Try to turn the L mixture screw (the one near the bottom of the carburetor on the air filter side, closest to the engine) 1/8 to 1/4 of a turn counterclockwise. These mixture adjustment screws ( L and H) have odd heads on them and conventional tools won't turn them. I use an automotive type plastic wire connector (around 22 gauge) with a ring terminal end which I can hold. Tap the plastic end of the wire terminal connector onto the head of the screw with a small hammer and this will enable you to adjust the L screw. This adjustment will increase you high speed side and possibly allow it to run off choke in a regular manner.

Starting problems . never used it before just need simple instruction


  1. Fill the tank with fresh properly mixed fuel.
  2. If equipped turn the switch to RUN or ON
  3. Make sure the tank is full of fresh fuel mixed per directions.
  4. pump the primer bulb until resistance is felt and fuel is seen pulsing through the lines without bubbles.
  5. pull the cord sharply and repeatedly until the motor "hits" on one of the pulls
  6. set the choke half closed
  7. pull the cord sharply until the motor fires and idles.
  8. allow the engine to idle until it will warms up and will idle when you slide the choke all the way open.

Blower will only run on full choke ryobi ry08578


They aren't designed to run with full choke on, the choke is for starting cold engines only, many times you can choke them pull the cord a few times and then turn the choke off or turn it down to start it. Then slowly reduce the choke until it runs fine on its own.
