Question about Ryobi Garden

Air fuel mixture setting for Ryobi 31cc engine. I changed out all the fuel lines because the old ones were dry rotted. After changing them out them out my engine will not stay running. I can see air mixed with the fule going into the carburator and then it stops running. I can press the fuel bulb and it will start up again, then as the air gets to the carburator it stops again. So what is the setting for the air to fuel mixture knobs on top of the carburator knobs set at?

Make sure your lines have been hooked up correctly. Take a look at the sketch and see if yours looks like this. air fuel mixture setting for Ryobi 31cc engine - d0e1722.jpg

Runs terrible misses loss of power and reading p0174 code.

P0174 means that you have to much oxygen in the exaust system. When your car is running your computer sets the air/fuel mixture for you to run at its best perfomance. Most causes for this propblems are; 1. MAF Mass Air Flow Sensor. 2. worn out/dry rotted/ leaky vacuum lines 3. posible EGR vavle but not real common & 4. low fuel pressue. You can clean the MAF with electrical parts cleaner but don't touch the wires and stuff and I would only use elecrical parts cleaner. It should be located in the air duct. Next I would check all my vaccuum lines including the EGR valve for dry rot and the such. The finally you might want to change your fuel filter if it hasn't been done in awhile as well as if posible check your fuel pressure. Disconnect your battery when you are taking the MAF off. I hope this helps and good luck.

I need the fuel/oil mixture for Ryobi 31cc 775r gas weedeater. Also the diaphram for the fuel line replacement.

The fuel/oil mixture is 40:1. That is 3.2 oz. oil/US gallon. Now for the fuel lines:

The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

Putting fuel line on right on ryobi 725r 15'' 31cc weedeater

Typical fuel line routing is:

One line (the one with the fuel filter in the end of it) comes out of the fuel tank2.gif and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb. The third section of line goes from the top fitting on primer bulb to top fitting on the carburator. Hope this helped and best wishes.

31cc ryobi weedeater wont start

I've had similar trouble. I removed the plastic cover to expose the fuel lines. I've had to replace all of them as each one had dry rotted, split or had holes. There are four runs of clear plastic fuel line. Check all your lines and then check for any of it being plugged up to the carberator. The primer bulb should develop some pressure when all is good.

Blowing gas out the air intake

Eight years is great for a weedeater! Blowing out can mean something is stuck in the reed valves, or one may be broken. They are just under the carb, usually. Be real careful with the gaskets. If you mess up any, silicone will do. Use good car gasket silicone.

Ryobi is Japanese for "Piece of ****" My suggestion is to throw it out!
My 767r has had fuel line and carb trouble from day one. I'll never buy another Ryobi or Craftsman tool again.
