glenc: I have about 35 years experience working with small engines. My son-in-law purchased one of the $430 X430 Ryobis a couple of years ago and it started doing what all of the ones mentioned in the emails are doing. I went so for as to purchase another carburetor, which was money thrown away. I have never met a challenge like this rascal has caused me. I even found a way to adjust the carburetor, but it makes no difference how you set it. I am retired now, and I may check out some of the things mentioned in the emails below about timing etc. Other wise, the units will make good trot-line wights.
Air Port: NEVER use a machine with bare feet. and try to grow a brain
Juan Mancha: I wish mine would start with or without a gas cap, bought mine at home depot 39days earlier and after their bad attitude,they wanted 20 dls. just to look at it. I just wanted to exchange it for another one the same , they said NO! so I called the factory and they gave me a local repair address,just take the proof of purchase......will see ! I will post the results. I was going to say don't buy any kind of tools from kreepot but nowadays there is no where to go for good service.
fujiobass: why you left the gas cap open ? because you want the dust go into the gas tank to have the carb will be stopped ? you should have the problem this way.
The Notorious Angler: I was waiting for that !!!
The Notorious Angler: cool i notice a lot of them bogging around the neighborhood guess folks are so used to 2 strokes what did it take to open it up
The Notorious Angler: all tiny 4 stroke engines will bog like that with the snap of the throttle
LegendMuscle: wanna buy another? s430
manolis papadadtonakis: he has no gas cap
KJYUG: Wind the low end(L) screw out half a turn....worked on mine
Bob OBrien: how to set timing after putting belt back on ryobi s 430
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...
