Robert Goodwin: I am working on a Ryobi x430 the belt come off the valve cam. It start but low compression. Changing the timing belt on these are not worth it. Do you have a problem with your weedeater doing that.
With you're weedeater sound like need carb cleaning or something else. I like the 2 stroke better.
brian morris: Hi, My Ryobi RBC430 SBS ( 4 STROKE MODEL) timing belt has slipped off the top cam shaft timing gear. There does not seem to be any other problem with the machine but I'm unsure with it being a 4 stroke engine about aligning any timing marks up prior to attempting to re-start the engine. Can you advise at all ?
the urbon redneck: run some rubbing alcohol through it. if that doesnt work, clean the carb and change the spark plug
irmux skeptic: have same trimmer , and blowed like in your move, on my trimmer was half shaft * and bottom finger fall out, piston with stroke vent down and hit crancshaft and broke piston :( there is cover from behind like 8 screw open and look inside
AbortedEvolution: Mine's been a non stop hassle. Work great for a year, been crap ever since.
charles burton: Not really another trash find you just don't know what your doing or saying...after a few hours of use I leaned out the mixture. NOTE almost everything you buy with an engine has a break in period and is calibrated rich from the place of manufacture...
Cody Johnson: Hey when you gave it gas it went from run to choke. I have the newer model and they chenged the switch.
leader562: you need to adjust the valves before you lock it up
rz1031twu: I have S430 and its a POS . It start about 10 min as you pulled the trigger the shaft would not turn at all then engine died out... I smashed it with an ax,then to the trash bin
503technics: My s430 has a metal camshaft! it is 2 years old and i just had the motor apart.
Robert Hammond: Home depot is my favorite place to get "stuff". But it should make them a little concerned to be marketing such trash as this weed eater. It is he worst.
Robert Hammond: This machine was purchased last summer (2012). I used it no more than 7 times, SEVEN. This machine is a piece of junk. If you purchase one be advised!
Carlos Pereira: Anyone know if they make replacement metal camshaft for the S430?
Sean Leach: I too have experienced the same problem, but I've been able to 'tease' the throttle a bit to get through the stall. Non the less, it does stall often on a cold start. Another problem I've encountered is the priming bulb rotted away. I was able to replace it at HD though. All in all its been a decent machine. I wouldn't recommend it for landscape maintainers using it daily. It's not up to that quality. It's an affordable tool for home use with the benefits of being 4 stroke, and attachments.
beachbummm69: just got one from a yard sale with the edger head for 2 bucks, they said the motor was locked up...I took the plug out, pulled the cord, replaced the plug and its running fine...maybe they stored it standing on end and it "hydro locked" somehow. IDK but for 2 buck Ill run it until it dies. they are all china crap anyway.
Steve Haller: I just purchased (July 2013) a RY34446 (S430 I believe it is according to the manual front cover) although S430 is not marked on it. Seeing the concerns about the S430 and plastic camshaft, I contacted Ryobi support and they assured me (in writing) that the S430 models have a metal camshaft. I have not inspected it close enough to confirm, and I suppose I would need to pull a head cover to do this, but based on my s/n and unit MFG date of 03-15-13, they confirmed that it has a metal cam.
fret master: High adjustment -If this does not work after opening it up Then open the carb and clean out the Jet .Many times during assemble in china a bit of debris gets in the jet .
01Commenter10: its too late.. You already destroyed the piston rings. You can drain the oil and re-fill it with the proper amount of oil but oil will STILL bleed thru the pistons and shoot out the carburetor….
DO NOT OVER FILL with oil… just put in what it says to put in, its a small crankcase and does not need that much oil.
My newest X30 just failed cause the cam gear sprocket (made of plastic) melted and the cam gear fell off causing the timing belt to fall off, now its trash.
John Davis: It actually started.. smoked.. and blew oil out all in about 30 sec before it quit..
John Davis: I had my trimmer fall over in my garage and a decent amount of oil drained out through the carb, I refilled it (overfilled).. now I had more oil blow through the carb. I drained some oil out but now it will not start. Any suggestions?
