Scott Ewing: Change the spark plug, and buy 89 octane or higher at a good brand gas
station. BP or Shell is best out there.
Worst possible scenario is that you have a bad carb. I have an X430 and it
These engines do not agree with pour quality gas the way a 2 cycle will.
the urbon redneck: run some rubbing alcohol through it. if that doesnt work, clean the carb
and change the spark plug
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...
AbortedEvolution: Mine's been a non stop hassle. Work great for a year, been crap ever
Cody Johnson: Hey when you gave it gas it went from run to choke. I have the newer model
and they chenged the switch.
mynonsense: Peice of doodoo!!!!!!!!
skepto anti: 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
leader562: you need to adjust the valves before you lock it up
SpeakerPolice: That is unfortunate. I suppose there is a chance the one you bought was old
stock, still on the shelf, but still, this isn't promising.
187hoser: Go to the Ryobi website and check for a pdf of the manual. There are
instructions in it for carb adjustment and for rocker adjustment. I just
bought one and I hope it runs better than this one you found. It also
mentions cleaning the spark arrester too when there is a loss of power.
Jonathan Oxlade: 2stroke petrol needs oil while the 4stroke runs on pure petrol
SpeakerPolice: WOW! 10 grand per engine?! Holy crap! xD I got the Pacman tool in today.
I'm making an updated video soon; I now need new fuel lines and primer
bulb! they deteriorated in the old gas for some reason!
SpeakerPolice: That's possible, even probable.
SpeakerPolice: Do you think if I went to Home Depot right now and purchased the current
production X430 head, it would run better than this one? (Not saying I'm
giving up on this one; I actually don't even have spare cash!) I just want
to know if they've worked the 'kinks' out. :3
SpeakerPolice: I wish I could help you. I'm still stuck myself. xD (now it needs a new
primer bulb and I can't seem to find one online)
Arnaldo Maldonado: Check to see if this trimmer uses a plastic timing belt. If it is there you
will see that there is not a timing belt tensioner. If this is your case
the problem is that the timing changes when you aceletate or desacelerate.
This kind on trimmer is a piece of garbage ( sorry for the comment).
tony c: Well then I'll be looking up an authorized repair shop to see what they
say. I got my Amazon receipt so hopfully I'll get some service! I sure hope
then can help me! Thanks for the infomation TC
arabiantxn: @8191921 It almost sounds like a conspricy but, i think over the last 10
years american manufacturers have resorted to making low quality products
that don't last long in the selfish interest of profitability. I have had
similar experiences with Chrysler i had purchased within 4 years of
purchasing a 33K new car its has become a garage queen. That said i still
have full faith in Ford and craftman and their products
RANEYDOG: To tjcarita. Call a ruining service center and they will have you bring it
in. Bring your purchase receipt and they will submit it to get you a
replacement. I'm waiting on mine but should take about 2 weeks. I will let
YouTube know how it goes with a video.
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.
SpeakerPolice: Sad, but believable. I wonder if they'd get penalized by the EPA otherwise.
I went ahead and ordered the Pacman tool last night--still having trouble
locating that blasted primer bulb! I'm beginning to think it might be right
under my nose--nobody supplies compatible model numbers!
shadowman944: Remove housing then take off valve cover it's. 1 screw and look at the
camshaft what do you see and let me know at shadowman944@AOL.com
Steven Farago: My Ryobi exhibited the same problem: I opened the head and the camshaft
-that was made of cheap plastic- totally disintegrated and did not lift one
valve. Cheap junka nd poor workmanship. No easy fix or replacement, but
SpeakerPolice: Which did you buy, C/S430, or the X430? If you have the X model, it should
be fine. I'd return the other two models.
Stanford Douglas: It's a pressurized system! Won';t run that way. Plus the carb is set for
emissions not best running. A Pac Man tool (Ebay) is needed to adjust the
high and low speed settings. Or you can use a Dremel tool to cut a slot in
the 2 needles. You also cut through the carb housing around the 2 needles
to do this.
FiveCentsPlease: Google seems to show some places to purchase the pacman screwdriver as well
as the other shapes. There are also a few YouTube videos for rebuilding the
carbs and these are a good reference.
SpeakerPolice: Thank you very much! I will hopefully have this engine running again at
Derek Figueira: Glad you found one! I checked both of mine, neither of them have an air
filter. Also note that near the oil filler cap, the instructions say to use
20W50 instead of 10W30!
Stanford Douglas: Once you have that set both the H an L needles at 1 1/2 turns out. Set the
low needle, closest to the engine (look closely they are marked on the carb
housing). Set the L by turning it in clock wise until the engine speeds up,
then back off a1/4 turn. Note the position. Now turn it out counter clock
wise until it slows way down. Turn it in a 1/4 turn. Note the position and
split the difference. Now go to full throttle and turn the H needle clock
wise until it speeds way up.
addii578: bro turn ur idle screw down its idling a bit high and invest in a gas cap
that could be dangerous unles u were just running for a quick vid if u need
any help on how to adjust anything feel free to send me a message or throw
me a comment i can help out alot with small engines
SpeakerPolice: I am beginning to believe this is true...xD
SpeakerPolice: Looks like I will be forced to purchase a new X430. My father threw out the
one I spent so much time on. >_<
speed10641: This is what you do go back to homedepot and get a replacement primer bulb
kit it comes with new fuel lines and filter and primer bulb put them on and
use non eth fuel mine runs like a scaled dog
01Commenter10: The C430 and S430 models all have a plastic camshaft… the exhaust lobe will
get damaged and cause major problems… The X430 is the newest model with a
metal camshaft and i have had it for over 18 months problem free..!!
FRINGEWATCHERII: CARBURATOR NEEDS TO BE ADJUSTED
SpeakerPolice: Everyone tells me that. xD I found it without one; it has one now, but now
the primer bulb is shot. >_<
1oldarmyguy: I have the same model. And after 3 years of service it started to act up.
Carb adjustment and added some sea foam gas additive, works great.
chett1983: You would think such an inexpensive component, that you would surely sell
to the consumer many times throughout the duration of the product would
actually be profitable
SpeakerPolice: You might be right!
Mykdee: Mine runs exactly like that...it's a shame, cuz I like it other than not
1spaman: Carb needs adjustment.
SpeakerPolice: So, Home Depot actually sells a kit containing everything I need? That
would be great!
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.
bretts1stuff: hay i have the same one did the same thing i ript it apart the eqevlent to
a car crank shaft is plastik and it was wore in flat im still trying to
find it pless let me know how it gos
SpeakerPolice: Unfortunately, my father threw away this machine recently, before I was
fully able to explore and explain the issues on a video for YouTube. D:
SpeakerPolice: Really?! People are putting these things in model aircraft?! They'd be HUGE
in one of those, I'd think! I wanna see that! xD I will look into those
part numbers, and see if I can't find the parts I need. Someone mentioned
needing a special tool to adjust the pac-man screws on the carb--any idea
where I would find such a tool?
Carlos Pereira: Anyone know if they make replacement metal camshaft for the S430?
Stanford Douglas: In the first place the Ryobi S430 pressurizes the tank. That's not going to
happen without the cap on the tank. Second the S430 has the high and low
needles set to pass emissions testing and is running too lean. In order to
set the carb you'll need a "Pac Man" tool. Available on Ebay from $10 to
$20. The needles are marked L and H on the carb body.
tony c: I got my Ryobi from Amazon.com May 10, 2010 . Are you saying take it to a
service center and they will fix it for free even after having it for 2
years because it has a plastic camshaft?
photochick: @SpeakerPolice You are right; fetishes of the feet variety are popular.
Just ask Rex Ryan, the coach of the New York Jets who posted videos of his
wife's bare feet on youtube (in case you hadn't heard).
