if worn need to replace it

Take it back. If the new one doesn't perform like it should get your money back and buy a Stihl. They will fuel and run the machine before you ever leave the dealer with it to make sure it runs like it should and they can answer any questions and even get you parts. Husqvarna may do the same thing If you need further help, I’m available over the phone at https://www.6ya.com/expert/kelly_69a0cf1b13789df1

I have this machine and it states it requires 4 ounces to 1 gallon gas. This is if you use the i.d.c.oil which is 32:1 it states if other 2 cyc oil is used it requires 6 ounces to 1 gallon fuel. Im trying to add a picture of the machine. I have aryobi 720 sieries. The newer ryobi machines call for the 50:1.

Put a tarp over it

Typical small engine carburetor initial setting is 1.5 turns for both high and low needles. Turn in the idle speed adjust to open the throttle for easier start and run until the low speed air fuel mix is better adjusted. If you treated the fuel with Seafoam do not overdose or guess. Seafoam has a significantly higher specific gravity making it more difficult to draw up for atomization. Better to use untreated fuel until carb adjust is completed.If it runs for awhile with choke then likely the impulse fuel pump is working so the carb gasket orientation is correct but double check the impulse air passage is aligned.It's always a good idea to replace the fuel filter and fuel lines. Be careful to not get the filtered fuel line wrong or any debris in the tank may be drawn into the carb and plug the internal fuel screen. Telltale for a plugged screen is the purge bulb is difficult to depress and rises extremely slow.

I been having the same problem with mines as well and it smokes sometimes when it cuts off

Check YouTube for applicable video.

get the carb serviced. Could be fuel overflow. small engine carbs are very finicky if left sitting for too long with fuel remaining in the carb.

big chance you will wreck the motor from lack of lubrication .

It coud be and it could be lack of compression or a blockage somewhere.

If you do add oil, it should be 80w or 90w I would think. Do not put 2 cycle oil or gasoline in your gear box like the ones above mentioned unless you are purposely trying to tear the gears out. Mantis cultivators use Lithium 0 grease in theirs (Mantis Original Gearbox Lithium Grease #9985)

60 is extremely low for a 2 cycle. Make sure throttle is wide open when you do the compression test and remove spark arrestor.

If still 60, try squirting some motor oil into the cylinder. If compression jumps up then rings are shot. Otherwise check for crankcase leaks.

check bearing on side not running smoothly and not getting up to speed

I need the same schematic for Ryobi sx1

probably needs greased

e-replacements parts probably https://www.google.com/search?q=ryobi+c430+parts ..

only place I know that sells them is our home depot stores . But I would search using google

Here was my solution:
I was having problems with my ryobi cs30 weedeater also. It would start up fine on full choke, but i could not give it more than half throttle or ever take the choke off or it would stall out. I replaced fuel mixture, spark plug, spark arrestor/exhaust, fuel lines, cleaned carb, and still nothing! I was considering getting a better machine. Then i decided to play with the carb adjustments.(on my cs-30, they are two screws on the carb that have a "L" and "H" next to them) I dont think you can get the specialty tool for adjusting the carb unless you are a repair tech, so i just took a Dremmel tool with the circular cut-off wheel to the head of the specialty screws and made them into "flat-head" screws so i could adjust them with a regular screwdriver (if you dont have a dremmel too, get one!) (As i was cutting into the head of the screws, i also cut into the casing protecting the head of the screws that was in the way, this does not cause any damage to the unit, that casing is only there to keep "un-certified" people from adjusting it for themselves.)
Now to the easy part: The "L" screw adjusts the idle fuel mixture and the "H" screw adjusts the full throttle fuel mixture. turning the screws clockwise make the machine run leaner (less fuel) and counter clockwise makes it run richer (more fuel).
-I started out by turning each screw 1/2 turn counter clockwise and started it up, then as it was idling, i started adjusting the "L" screw as i was moving the choke position to run, after a few full turns counter clockwise of the "L" screw, it was idling perfectly in the run position, then i did the same thing the the "H" screw while holding down the throttle and i got it to run perfectly in the run position. Now it is running way better than it ever has. I hope this helps everyone.
Good Luck!
