Thread: Engine Problem..... on Lawn Tractor

Probably a valve and replace it with a John Deere (or Trigreen )

Pull the carb and check to see if there is a non-floating float, stuck needle or leaky O-ring. If the carb keeps letting gas in, it will flow into the cylinders and past the rings to the crank case. Floats can leak, the control needle can be out of it's seat or the tab bent over time, or an o-ring is leaky and by-passing into the float bowl. It might be a 10 cent part, so I'll look there first --- probably running that ethanol stuff in it and ruined all the seals

just fixed the neighbors mower, same exact problem. Needle was sticking and flooding the motor.

Yeap Briggs.....

I drained the oil entirely..... filled it with oil.... fired right up.

Got the lawn mowed... I am sending it to get the blades sharpened and the deck leveled.. this week too... so I will have him look at it.

It may be just a piece of trash in the system, but usually it needs the needle and seat replaced and a good cleaning.
