Common problem is the fuel pump. It is a small diaphragm in the carburetor. The diaphragm deteriorates, especially with the alcohol in the gas now. You might rebuild the carb. The kits are about $20. Other problems include clogged fuel tank vent, clogged fuel filter (on the end of fuel finder hose in the tank, and clogged fuel jets which is less common.

What causes my 231 echo to lose power when i hit the throttle, changed sparkplug, filter plz somebody..

Robert - It sounds like your unit will crank and idle but does not want to run up when you give it some throttle. It sounds like to spark arrester screen behind the muffler may be clogged with carbon (which is a very common issue). The idle speed exhaust is getting out but not the amount of exhaust when you try to throttle up. Remove the bolts/screws that hold the muffler on. You will see a small square or rectangular screen at the exhaust opening. Remove it and hold it up to the light. If you cannot see light through the screen, it's probably clogged with carbon. Soak it in some lacquer thinner or some acetone to dissolve the carbon. Brush it with a wire brush if you have one. Recheck to see if the screen is clean of carbon. The object of the cleaning is to get the spark arrester screen to allow exhaust to exit the engine as you give it more throttle. The spark arrester screen catches red hot pieces of carbon that try to come out the exhaust and can, under the right conditions, set the grass on fire. If you live in an area that is prone to wild fires, make sure you clean or replace the spark arrester screen for your safety. Here is a tip: When you get you unit back to running good again, run the throttle at full speed when using the equipment. This helps to keep the carbon from building up on the spark arrester screen. Give this a try and stay safe :-)

Why won't my McColluch weed eater create a vacuum

Did you check the muffler exhaust or spark arrester, to see if it is clogged from using to rich a oil/gas mixture ? Did you replace the diaphragm in correct position ? Find a new carb online, possibly ebay ?

How can I clean /remove muffler & spark arrester on my ryobi cs30-ry30120 ?

There are two torx head screws in the muffler. If you take these out the muffler comes apart.The first thing to come off is the outer cover of the muffler. After that there are 3 more screws (the part description only says pan head) that hold the outlet tube on, under this outlet tube is the spark arrestor screen. You can clean the screen by heating it up until the carbon on it turns a red/orange color, then blow the screen clean. I would suggest a propane torch from Wal-Mart and a pair of pliers to do this. Then re assemble the muffler. I have included a link to the Ryobi Parts breakdown. You may have to put your RY30210 model number in the search box. The diagram you are looking for is the Engine Assembly. I hope this gets you back to running again. :)

Smokey 2 cycle oil will cause the exhaust ports to carbon up and plug the spark arrestor.
Remove the muffler, use a pick to clean out the exhaust port on the engine, and the muffler inside opening, then clean the spark arrestor screen, to assure yourself you are correcting the problem start the machine up with the muffler off, it should run like a charm, if it goes back to running badly when you reattach the muffler it may be clogged on the inside.

If you have a spark arrester fitted, it will be blocked with carbon preventing the exhaust gases leaving. It will be behind a plate bolted to the exhaust silencer/muffler. Scrape the carbon off the wire mesh carefully, until you can see through the mesh again.
