Can you Regulate the Engine Speed Using the Governor Arm? If Yes, then Reset the Governor. **To Reset the Governor; Loosen the Governor Arm Bolt and Turn the Governor Shaft Clockwise Until it Stops. Using the Governor Arm Hold the Carburetor to Full Throttle. Now with the Shaft Full Clockwise and the Governor Arm and Carburetor Held at Full Throttle, Tighten the Governor Arm Bolt. If the Engine Still Runs Full Throttle, then Reverse the Rotation of the Governor Shaft, but Still Hold the Carburetor at Full Throttle with the Governor Arm. If it Still Runs at Full Throttle, then Check the Internal Governor.** If you Can Not Regulate the Engine Speed Using the Governor Control Arm, then Check the Carburetor Throttle Valve. If the Throttle Control Valve (sometimes called a Flap or Plate) Mounting Screws Came Out of the Control Valve, then you will have No Control Over the Engine Speed. Send me the Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you. **The Throttle Cable Attaches to the Throttle Control Bracket. The Cable Moves a Slide that Moves a Pivot. The Pivot has the Spring Attached to it and to the Governor Arm. The Solid Link Connects to the Governor Arm and goes to the Throttle Shaft on the Carburetor. When the Throttle Cable is Moved it Moves the Pivot and the Pivot Pulls the Spring. The Spring Pulls the Governor Arm and the Governor Arm Moves the Throttle Shaft. Usually the Spring is in the Lower Hole in the Governor Arm and the Solid Link is in the Top Hole of the Governor Arm.** If you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens

The oil is contaminated with water. Change oil and filter, if it has one.

these are common for doing this ,if you dont want to pull it down and hone the cyl. then i would use a heavier oil say 20w/50and that will probabley solve your problem

Misfiring could be caused by simple things like fouled or worn out sparkplugs or an ignition system that is slightly faulty or Fuel problems such as dirty or stale fuel or clogged filter causing a leam mixture. Some B & S motors have an switch that cuts the Ignition if the oil pressure or oil level is low.
Another cause could be the Valve clearances are out of adjustment.
