Briggs and Stratton 17HP Intek Governer Overspeeds

I am working on an Yardman by MTD Riding mower with a 17hp Briggs and Stratton V-Twin engine. I repaired the starter and on start up the Governer goes to wide open. What is the procedure for setting it properly so it functions as it should? Thanks, Ed

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

How do I remove the piston from my Briggs and Stratton 17hp horizontal shaft mower?

if the piston big end bear is removed and the piston will not come out of the bore because something is stopping it , it will be from a wear ring area at the top of the bore (wear ridge)
it is where the top ring stops and there will be a lip down the bore the distance from the top of the piston to the first ring
all cylinders wear big at the top to normal at the bottom ( wear taper) and the ridge is formed over time from wear or in the case of small engines from a failed air filter which allows accelerated wear of the bore ( dusted engine) and produces a ridge that the top ring jams on so preventing piston removal
to remove it you can buy a ridge remover tool from a good tool shop or auto spare shop or you can get a small grinder wheel in a drill and just grind the lip section off.
provided you restrict the grind to no lower than the lip it will not affect the engine

How to rebuild a 17hp briggs & strattion motor

Get the date code and model off the rewind cover, Jacks small engines sells kits complete along with others. If you are a hobbyist go for it but in the long run is it a greater value to purchase a short block instead.

Briggs 17hp intek overheadvalve on a john deere L100 has developed a hard start hard spin on compression stroke. new battery new starter

hi there

pauly46 here

if engine seems to labour when trying to start as if too much compression ?

try adjusting to in and ex valve clearance to 0.003" inlet and 0.005" ex

inlet valve is the bottom valve, and has a alloy push rod. ex valve is top valve and has steel push rod ( as viewed from the front of the machine with rocker cover off ) )

note rotate engine with plug out to tdc compression stroke , then rotate it down the bore on power stroke by 1/4 inch ( 6.35 mm ) this is the point for setting in / ex valve clearances

manual says 1/4 pst tdc on compression stroke - this eliminates decompressor lift from the setting

cheers hope it hepls

Lawn Mower won't start

Its a thing of beauty to see problems solve themselves. It seems to me this trial and error approach is very taxing and could have been avoided if 1, your small engine repair guy/Craftsman/Sears had sold you the right parts from the start, or 2, you had bought the right part... from the start.
