Question about Ryobi 30 Cubic Centimeter Curved Shaft Gas Trimmer

1 Answer

Ryobi CS30 will start but when I pull on the Throttle trigger it bogs down, good spark plug and filter is good. I have the same problem. Cleaned everything and even put NEW mixed gas in and still does not stay fired up. Even messed with the Idle off and on and got nothing of a better result. Contact Ryobi if it aint running right.

Check the fuel lines first for cracks. If they are cracked or brittle, replace them. Also, your carburetor may need cleaned. Use a Den Tek Brush, (used for cleaning between teeth), to clean the small portals. Make sure the small screen in carb. is free of debris. The smallest of particles can cause your problem. Reassemble and try starting. If it still acts up after all this then you will have to purchase a carb. kit and replace all appropriate parts. If you need tips on these remedies, feel free to ask.

Echo ES210 Blower will not start


Since you are getting spark from the plug it sounds like a fuel problem. I would check all the fuel lines and make sure they aren't plugged and ensure the filters are clear.

Blower bogs down and kills at full throttle


Check the following, then clean or replace:
  • Fuel Filter - Located IN the fuel tank
  • Spark Plug
  • Spark Arrestor - at muffler port, creates resistance of exhaust flow, engine then bogs
  • Carburetor - may need a rebuild kit
Then watch this...

Ryobi CS30 - Stalls out?


Dirt or varnish in fuel filter or carburator. Change filter if there is one.

Flush out the carb with a varnish remover.

Open high speed needle valve 1/8 turn farther, then turn in while running until it just smooths out.

326rjx bogs down when you pull the trigger .cleaned air filter and spark plug new gas and oil mix what do you think?


Sounds to me that your high speed needs adjustment. Usually by turning it slightly out will take care of this but don't turn it so far that you lose quick throttle response.

Engine starts but dies when I pull throttle trigger


you need to adjust the high speed needle turn it out in 1/4 increments as you throttle it, low speed may have to come out alittle but do high speed first. I had to answer this as I use to have a pastor john in sturgeon bay, miss him alot.

CS30 Ryobi trimmer dies when I press throttle!


Yes. You just need to do a simple carburetor cleaning. Disassemble the carb. and spray with carb. cleaner. Make sure the small screen is in carb. is free of debris. Use a Den Tek Brush,(http://www.dentek.com/shop.php?target=products&product_id=7), to clean the small portals in the carb.
If you need further assistance, just let me know.

I HAVE A MODEL775R RYOBI GAS TRIMMER 31CC IT HAS NO SPARK.


you probably made the mistake of leaving it in the shed over winter with gas in it.
in the carb there is a diaphgram that oumps this fuel in via the motor vibrations.
said diaphgram had been ruptured due to drying gas in the carb. the solver to this is to either have a small engine mechanic replace it or the whole carb or get a new one, and i would suggest you get the cs26 model instead. i have a cs30 and cs26 and i have had less problems with 26. it only has two chokes.
you prime it.
you push lever to start, closing all but a little bit of carb,giving engine much richer mixture.
you squeeze trigger, opens halfway/full, as there are two chokers in the carb, on controlled by lever and another by throttle.basically now you haave half choke.
you release trigger, goes back to 7/8 choke to keep at idle but not running. your ready to go.
on the cs30 its much more complicated:
ful choke
prime 7x.
pull 4x
half choke
pull till start.
wait ten seconds of running at idle rotate to run
good to go. but these guys have porr design. if you take off the back cover and look above fuel tank on cs30, the crank is RIGHT SMACK THERE and not better secured like in the '26 model.
that's what the little circular hole is in it.
anywho, the diaphgram is ruptured, and you probably haven't noticed that in addition you have gas leaking out the carb's air intake.

i know what u guys got going here. you proably left it i the garage over winter with gas in it. maybe not. anywho, there is a diaphgram in the carb that pumps the fuel in via vibartions of the motor. poor design alont ith fuel filterINSIDE AND AT ONE END of the gas tank. anywho, this diaphgram is ruptured, and i bet there's also gas coming out os the carb and dripping off the choke selector?
this is a job for a small engine mechanic
