Question about Ryobi RHT2660DA Petrol Hedgetrimmer - 26cc Quick Fire Engine

Open Question

I have a Ryobi RHT 2660DA Hedge trimmer that will not start. I have tried the following things; 1. Replacing the spark plug. There is a good spark on both the old and new plug. 2. Adjusted the carburetor as suggested. 3. Put a teaspoon of fuel into the spark plug hole directly. Does not even try. 4. Tried easy start in the spark plug hole directly and into carburetor. No joy. 5. Took off carburetor and cleaned a suggested. No joy. 6. Replaced the available diaphragms (4 in all). No joy. 7. Replace carburetor with a new one. Same result. 8. Checked compression which was only about 50 per square inch. 9. Checked tightness of crankcase screws. All tight. 10. Replace crankcase gasket. Still same compression result. Again no joy. 11. This machine is about 5 years old but only used about 5 or 6 times so should not be a wear problem. 12. Replace mixture (did this early on in the sequence) 13. Took off exhaust which was full of fluid. Cleaned and dried, but to no avail. 14. Stripped unit down as I started to believe this was a timing or compression problems, but I cannot get the bottom clutch unit off (do not know how to remove it as it looks like an interference fit on the shaft. As a result I cannot get to the flywheel to see whether the key way or key has sheared or the timing has somehow moved. I am now at a lost of a way forward. I would appreciate any help or suggestions. At the moment I am left with what is an expensive piece of junk.

I have cut the extension cord when using a ryobi RHT-600R hedge trimmer. It now won't work when using a new cord. Is there something I need to reset?


Was it plugged in to an outside receptacle? If so are you trying to plug into it after new cord? Try a different receptacles if you want to be sure go inside the house and plug it in. Try it. If it works. The outside recepticles are on a GFCI circuit an have a test and reset button on it reset it if it does not work check the panel box for a trip breaker turn it all the way off then on again to reset breaker.

I have a ryobi hedge trimmer RHT 2660 DA why wont the pull cord wont return ?


If you can try and tap by the starter housing with a small hammer and then you need to get some lubricant spray injected in to the spring. If it wont go back in there is a chance the spring has either broke or become unseated.

My ryobi cs30 gas trimmer (3 years old) has been difficult to start this year, has been getting worse all year and now wont start. What's up?


Most likely it is the spark plug, but could be a dirty fuel system. I'd start with the spark plug then go from there. you can also use a good quality fuel injector cleaner in your gas to help keep all your small engine carbs clean. If the problem persists there is a fuel filter inside the gas tank that plugs onto the end of the fuel pick up line that could be clogged. Worst case a carb kit can be gotten for them for about $20 bucks. Hope this helps. Please vote yes, thank you.

Have zrry30550 Ryobi Hedge Trimmer (reman.) I have good spark,good prime-up, but no fuel into the cylinder. Please help.


Hello. Get a can of starter fluid and a helper. Spray some into the air cleaner and start it up. Have your helper continue to spray a little starter fluid to keep it running for a minute or so. This will clear whatever blockage you have. Once it sounds like it is running well stop adding starter fluid and see. Joe

What should the voltage be from the spark plug lead on


Unless you have a meter that can read in the thousands (yes, THOUSANDS) of volts, it's a moot point. If you fear your spark is weak or non-existent, go get an in-line spark checker and test for spark.

Autoparts stores, Harbor Freight, Northern Tool, all these sell in-line spark checkers. They are easy to use, all you do is remove the spark plug wire and connect the checker to the plug and the plug wire. If there is a sufficient spark, the light inside the checker will flicker when you crank the motor. If you see that light, you have good spark, also known as - voltage.
