At some point that Craftsman tiller will run out of gas and shut off, but that is no way for a tiller to function. I am providing a link to help you with this issue. An expert will be with you with additional information within 24-48 hours.

Thank you for your question on the running of the engine on the roto tiller.

It sounds like the engine is hunting which means that it is on the very edge of running to lean but when the governor kicks in it will reduce the hunting of the engine because you are now adding the power circuit to the fuel supply.

You have a fuel mixture screw on the carburetor I would suggest that you open it about 1/4 of a turn counter clock wise and that should solve the problem. This adjustment screw should be right below the idle adjustment screw.

Please let me know if that helped and if not we can continue troubleshooting with that information.

You can answer on the same thread without submitting another question.

I tried your answer and adjusted the fuel mixture screw and It had NO effect on the unit it still surges just the same. I even tried to adjust the screw up and down to see if it would effect the running of the motor and it did not. The one thing I did noticed after I started the rototiller was if I fiddled with the choke knob I could get the unit to stop surging. It was not the smoothest and did have some back firing but this seems to be the only thing I have found to this day even with the answers given by the experts that have effected the running of the motor in anyway.

Thank you for the update Pat. I am sorry that the engine is still not running correctly. Fiddling with the choke gives the engine a richer mixture and will stop the hunting or surging. It sounds like the carburetor is still the problem. It old fuel had been left in the carburetor for some time then the residue has coated the internal passage ways of the carburetor and are difficult to clean. There may be another possibility and that is the float setting in the float bowl. It may be not allowing quite enough fuel in fast enough to keep the engine supplied with fuel. You may end up replacing the carburetor. Sam A.

Thank you for your question.

I am sorry you are having a problem with the tiller. I think you are having a problem with the engine dying when you move the throttle lever. If this is the case, I suspect a problem in the carburetor. What happens is the main jet or passage in the carburetor starts to plug up and the engine does not get the fuel it needs to keep running. If you are using fresh fuel, I recommend cleaning the carburetor. I found a video that shows how to clean the carburetor. Click here to watch the video. The video shows a lawn mower. Once you remove the carburetor from the tiller, the steps are the same. Remember to mark the holes where the linkage fits before removing them. Be sure to work in a well ventilated area.


I hope this is helpful. Please let me know if you need further assistance.


Thank you for using Manage my life.

Mark.

Thanks for sending the model number of the tiller.

I would replace the fuel shut off valve, fuel line, and fuel cap.

The fuel shut off valve has an o-ring that seals against the bottom of the tank when you screw it in. Be sure the sealing area is clean before installing the new shut off valve. I would replace the fuel line because you might damage it when removing it from the shut off valve. the fuel line might also be deteriorating inside.

The fuel line with new clamps is item 187A.
