Question about Yard Machines 158cc Push Lawn Mower #11a 034f200

1 Answer

Won't stay running

I have this older model and when I start the mower it blows black smoke and soon putts out. If I play around with the handle ( maybe the throttle )I may get it to run but it barely chugs and soon stop altogether. When I lift it backward it sounds as if it is running the right way but I have to hold it up to keep it going. What may be the problem?

Check the oil level. It may be overfull. If so, a carburetor problem may be allowing fuel to get into the crankcase.

Overfill oil


Did you turn the mower on end or over? If so change the air filter otherwise It sounds like the piston rings are worn out. Rings are cheep but unless its an expensive lawnmower I would just replace it.

Sounds like the automatic choke to me. When it acts up next time, remove the air filter, and observe the butterfly valve on the carb. Hold it open with a screwdriver, and see if it starts and runs. I have found that wireing the thing wide open solved my Toro problems. The mower is still under factory warrenty however, so you can always take it back! Hope this helps my friend!

The older chrysler products have a ballast resister on the firewall that is used for dropping the voltage to the ignition coil. During a start procedure, while the key is turned all the way in start position 12 volts bypass the resistor forcing a high output of coil voltage. When you release the key to the run position 12 volts goes ito the resistor & a lower voltage of around 6-7 volts comes out, & goes to the coil.
What happens, is the resistor breaks inside and no voltage is coming out the resistor. Thus only a start condition exist with no run.

Float isn't working. It is leaking past the needle. Try taking the float out and use a q tip to clean out where the needle valve go's. And inspect the rubber tip carefully. If it has any mis shape or grove. Get a carb kit and rebuild it. That would be the thing to do in the first place. because the gas bypassing the piston and going into the oil will be enough for you to get a new motor too.

My Troy-Bilt mower starts easily but not as powerful, stays on for less than 5 minutes and gradually stops. some black smoke is coming out


If the black smoke comes out of the muffler, you are burning excess fuel and could have an air filter plugged up to restrict air intake and cause the engine to run rich, therefor black smoke.

The black smoke is too much fuel, it is flooding out. Carb issue, I would pull the float bowl and clean carb, the needle in carb is stuck open pumping too much gas in.

White smoke and blade won't engage


Sounds like a low compression problem. The piston rings have most likely failed and oil is seeping past them and burning, thus the white smoke. An engine needs three things to run...Spark, Compression, and Fuel. Just take the mower back as it is still probably under warranty. Mike. Rate 100% please.
