We need the primer bulb for a ryobi tiller purchased around 2003, the number on the engine ia SN4031UB24RA:EM date602 code

The bulb part is about 1/2 inch high, maybe and inch round, the plug on the end has two long pieces and two little round pieces between the long like this (:) kinda
The machine this fits on is a ryobi hand held tiller that I believe also orginally was removable and also had another tool that could be added like a trimmer.

Air in fuel ryobi tiller

you will have 2 lines at the tank. 1 is the supply line with one end having the fuel filter on it and sitting at the bottom of the tank. it generally runs to the inlet side of the carb. the output side of the carb usually goes to the primer bulb inlet, the last hose usually goes from the outlet of the primer bulb back to the fuel tank but only goes in 1/8 to 1/4 of an inch. it should only be in far enough to seal the hole and allow the fuel back in to the tank

The primer pulls fuel through the carbruetor
So take your return line from the carb. and hook it to the inlet side of the primer and the other side
of the primer bulb transtions into the fuel tank.
You know when you have hooked it up right when you press the primer it fills with fuel and dumps back into the tank.

I need to find someone who can tell me on how to replace a primer bulb on a Robi Till/caltavitor, the one that on it is dry rotted. Can someone please help me? Thank you

If you take a small screwdriver and go between the primer bulb and where it sits you will see a metal ring that holds it in, use the screwdriver to take it out. It sometimes takes a bit ou patience. Before you do any of that look around the outside that housing and look for small tabs that you push on to remove the primer bulb. New ones just snap back in. I think if you take a closer look you will see what I mean. Hope this helps. Best regards and good luck.

You need a primer bulb for a WalBro Carb. I am from the U.S. so I can't give you the name of your local dealer, but here is the information you need.
If you have a small engine repair shop nearby they may have one in stock or can order it. If you do not have a good repair shop in your are, go to and search for " 2 cycle primer bulb" to see pictures and figure out the correct one.
Arnold (MTD) has this part number Arnold 490-239-0001
Stens (another big parts distributor) has this part number
Primer Bulb WALBRO/188-12-1
If your primer bulb is separate from the carb here is the WALBRO/188-512-1 part.

Ryobi Tiller, model RY60511A, will not start. Air

mine was a total pain. I yanked on the rope so many times, it flew out of the keeper,and when I replaced it I ran it UNDER the fuel tank cutting a slot in tank. I also blew out the primer bulb. AFTER the replacement tank I arrived, I discovered rolling the machine forward helped the flow to carb and did not require priming. Now I need to fix throttle cable. But all in all, a tough little machine.

Has Ryobi RCS 3535A chainsaw a fuel bulb priming

The numbers you supply don't cross to an operators manual but that is typical of Homelite/Ryobi. I'm going to make an educated guess that it does not have a primer system. Other Ryobi saws with primer systems include it in the specification. The 3535A does not. Close scrutiny reveals no primer.
IMO fuel primers on chainsaws are one more source of problems. In the USA ethanol additives attack fuel hoses. Without a primer routing is from the fuel tank directly to the carburetor and much simpler to replace. Primers on chainsaws operate differently than 4 cycle engines too. No fuel is injected into the carburetor or engine, its only purpose is to ensure the carburetor is full of fuel,
Typical Fuel hose routing:
  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.

I need a fuel line and a primer fuel pump (plastic bubble) for my Ryobi 31cc trimmer plus. Any idea where I can get the parts?

You can order them directly through Ryobi and pay a small fortune or you can go to any small engine repair shop and purchase the fuel line by the foot. I believe your primer bulb can easily be replaced with what your local shop will have in stock. The parts from your local shop will probably out last the factory parts anyway.

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.
