Toro recycler will run until primed gas is consumed.

This sounds like classic vapor lock. Heat from the engine is vaporizing the fuel in the carburetor before it gets into the cylinder. Next time it happens, try icing down the carburetor and fuel lines and see if it starts up.

The main jet of your carb is clogged and you need to open carb and clear the obstruction - spray carb cleaner on the bolt that holds the gas container to bottom of carb - also spray all the innards along with any tube that protrudes into the gas can.

Then using air compressor blow the sucker out and reassemble. That should do it.

Remove and clean the brass bolt that holds the float bowl on the carburetor. Clean out the bowl too. Use no metal objects to clean this bolt. It has 3 small holes...bottom...and on the sides near the top. Use carb/choke aerosol spray cleaner on it. IT can clog (esp. without an inline fuel filter on mower). Clean the bolt good, reinstall (not forgettting felt gasket between IT and the bowl) and your runnability problem and fuel flow problem should be solved as the bolt is also the main jet of the carburetor.

If you over fill the oil your mower will not start until you remove excess oil. This should be checked first, This is a much easier fix.

This almost sounds like a pinhole in the primer bulb but I need to know if you did the following. Did you remove the jet and venturi tube in the bottom of the carb. and clean the BRASS orifice hole and BRASS tube holes? If you did not then It will act just like the symptoms you described. Also check to see if your float bowl nut has holes in the side of it. IF it does then make sure the hole(s) are clean. Also make sure the fuel selector is all the way ON. Adittionally if the carb to block mating gasket is torn or not secure it will also perform as you stated.

Lastly the open the fuel air mixture screw on the side of the carb about 1/8th turn and see if the performance changes.

If the problem persists ....
This is dangerous due to the risk of fire but....

If you have any carb cleaner you can give it a quick shot in the nmating areas just after you start it before it gets hot to see if it speeds up. If it does, you have a vacuum leak. It is better to use an unlit propane torch if you have one.

P.s. If the problem does persist I will need your complete engine number to proceed in troubleshooting.

Dont know if this is the same problem but it may help. I've recently bought a used Toro 6.5 recycler and have cut the lawn 3 times with it. This third time it began to stall out on me. If I hit the primer button several times it would start up but then die again. I thought I'd have to pull the carb and clean it, ut after looking at a few problem listings online I realized it was probably just some trash in the needle valve. I managed to get it running again by first pushing the primer pump 3-5 times, then pulling the cord to crank it, then while holding the contact bar in place with one hand to keep it running I reached down and pumped the prime button a few times before it cut out again- after one or two tries it apparently flushed the trash out and it ran fine again. Had the same problem later and fixed it the exact same way, then went on to finish the yard.

recycler toro 6hp. 10 years old,little usage. Starts then stops, have to keep priming. Can anyone help?

I had similar problem and cleaned the spark plug and that seemed to have worked, but I think that may be a temporary fix because the engine still seems to be running unevenly. I feel that it must be a larger problem with the carb. If anyone can help this novice to adjust the carb or clean both carb and filter, or offer other solutions I would appreciate your assistance.

Hello:

There are 2 Possible Causes for this Problem.
1- The Carburetor Requires Soaking and Cleaning.
2- The Valve Clearances Require Setting.
