Ryobi cs30 weedeater won't start

doug7210May 22, 2006

I bought a new Ryobi weedeater over the weekend. After using it for about an hour, the engine died (like it was out of fuel, which it wasn't) and I couldn't get it restarted. Any ideas?

Not to offend your intelligence, but you did mix oil w/ gas?

Does the engine turn over?

Does the engine have a spark? Take the spark plug out and make sure it is grounded against the engine. Put the engine on and pull the starter cord. There should be a nice blue spark. Be sure you are not touching the spark plug as you do this (you will NEVER forget it again).

Is the spark plug wet with gasoline?

Finally, is the spark plug connected correctly?

I had the same problem with a 31 cc Ryobi Blower-Vac. After trying everything (and I DO mean everything) I and every one else could think of, I was ready to replace the ignition module. Just for the heck of it, though, I pulled the plug and squirted a few drops of 30w oil in the cylinder and replaced the plug. It started on the first pull. Smoked pretty good for a while, but after that cleared it ran just as good as it ever did, and now it starts just fine. Still haven't figured that one out, but at least it's running.

WoodsRunner, I bet that you had a slightly corroded/dirty spark plug wire connection. You corrected it when you disconnected and reconnected your spark plug wire.

Nope, I had replaced the plug and cleaned the connections long before. I use dielectric grease in all my electrical connections to prevent that sort of thing. Also cleaned the carb, fuel lines, exhaust screen, etc. and used fresh 2-stroke mix.
Starting it with the oil like that would normally indicate bad rings, but I also know for a fact that they are fine. Just another of life's little mysteries.

Either:
Take it back too the box and get your money back.
Or take it too an authorized dealer and have it checked out.
It could be something like a blown flywheel key which you are not going too fix yourself anyhow.

I fixed my Ryobi CS30 problem. I cleaned the air filter, and the spark arrestor, and the muffler. I oiled the throttle cable and I still could not get this thing to run correctly. I began to remove the carburetor and noticed that the whole cylinder casing seemed loose. It was very loose (about 1/16" air gap). It is amazing that I could get this thing to run at all.

I tightened the three bolts at the bottom of the cylinder casing, (you have to remove the rear black plastic cover) and now it runs like new.

The cs30 use's a flywheel with the key cast into it. and the cs 31 flywheel won't fit it. It also has a sorry centrifical
clutch, take the thing back and get your money and buy something else.

See if your shut-off switch is shorting out against metal. Some switches are defective too.

Ryobi cs-30's in a nutshell.(Engine problems only.)
Blown flywheel keys.
Loose cylinder screws.
Undiscovered carb adjustment screws.
Kinked fuel lines.
Scored cylinders from chips and debri, unfinished ports, air leaks, and out of place piston pin circlips.
And.....A 2 year warranty that any real Homelite dealer has no problem honoring.

The spark arrestor is located between the muffler and the exhaust port. The correct gas/oil mixture if 50:1

Where are the carburator adjustments screws? I see 2 things that look like they should be carb adjust screws but they don't have a slit or cross for a flat head or philips screwdriver.

itstim,

I have a homelite and my carb screws were just like yours. They had no slit in them, so I cut some slits in them with a dremel tool. Worked like a charm, and now I can adjust it to make it run better.

I cleaned the plug and tried ti fill up the tank with mixed gasoline, then started leaking from the bottom of the gas tank. Then I found a circular hole next to the gas line tubing. I feel like something like a washer or something missing there? All it needs to block that hole? would you recommend what I needed to do?
Thanks

hellobaba... there is a white plastic washer that goes over the supply line that goes to the carb. that holds the line filter down to the bottom of the tank and keep it from leaking. there should be another line going to tank that is the return line you need both....Hope that helps

add fuel stabilizer to the gas can before you put gas into your equipment. our gas has ethanol which eats carburetors.

Hi, I have just managed to find the answer to a similar problem with a blower/vac. Let me start by saying that I've misspent my life around 2-strokes and take these kind of problems as a challenge - my nephew gave me this as he had given up. I F****d about with all aspect of this, the carb, the coil, the exhaust and in the end the problem was the gasket under the barrel! I took the torq screws out and placed a washer under each to stop them from bottoming in the cylinder and therfore clamping the gasket and hey presto it starts first go and the carb progression is okay.
I don't say this is the answer to all of these problems but it certainly worked on mine, give it a try. Good luck.

Ryobi has had a problem the last couple of years with providing the wrong oil with some of their weed eaters which caused them to seize up after a short time. It's a known problem, but we still see them on the shelves at Home Depot. We found this out by calling Ryobi. Home Depot easily accepted the return, but we had to sort through the stock to find one with the correct oil.

I have 3 dead Ryobi weed eaters in the shed. I have experienced most if not all of the problems described here. I keep getting sucked in to buying another one since I have many the attachments. Finally after reading this blog I have decided it is just NOT WORTH IT. I just bought another 4 stroke Ryobi and am going to return it since I haven't opened it yet I AM GOING TO PAY THE EXTRA BUCKS AND BUY AN ECHO! Best luck to all!

4 strokes usually are alot better. I got one I've had for 11 years and haven't done anything to it except change the oil and put gas in it. Starts every time on second or third pull. Would I buy another??? probably not. Seems Like they get cheaper as the years go by????? How I don't know but they manage to do it!!!!!!!!

May sound like a stupid question but my cs 30 won't start and I drained the gas tank first. Then I saw two lines inside the gas tk. one had the fuel filter attached at the end of the line. The other only goes into the tank about maybe 1 inch or inch and a half at the top of gas tank. Is this short line supposed to go in further?
