What is top no load rpm for v twin 25hp briggs intek

adjust the carb to governor linkage

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 spring goes on the second whole in the govner rod at the bottom of motor.

Sometimes the governor gear inside the engine breaks and you have to replace it. Did you try to adjust the governor by putting the throttle full and unloosen the screw on the governor arm and push the governor piece the same direction as the throttle opens and tighten the screw.

Besides the service manual you can view parts diagrams at a dealer like www.arcolawn.com. You can purchase the service manual at a dealer and it will show you how to hook it up.
The throttle linkage hooks up to the throttle shaft closest to the engine. the governor spring attaches the governor arm to the throttle linkage.
The choke cable attaches to the shaft farthest from the engine. I hope this helps.
PS your engine has two factory service bulletins on it.

Just guessing here, but if there is no control of the throttle and the engine over revs, then more than likely the governor control is broke. Briggs if famous for that problem. Governor is around 25 dollars and a lower crankcase gasket. Requires the engine to be pulled, lower crankcase removed, remove all pieces of old governor and then re assemble with new governor and gasket.////Before doing all this check that both springs are on the governor on the exterior of motor. If you manually hold the governor arm back, counterclockwise, and it still revs, then you need to replace governor. Don't let it rev for long or it with throw a pushrod or worse. good luck

A big vavume leak and or the throttle blade doesn't close or it gone ( missing). the carb should close all the way ( you can't look thiugh it) with the linkage off you should be able to run it by hand with good results. if you can find out the correct way to put the springs on and just move things around or gat a look at one thats working right and you may see whats put together wrong on yours.

Check for a broken spring on the governor linkage, follow your throttle control cable down to where it attaches to the throttle mechanism. In behind where the cable attaches you should be able to see a spring on the governor arm, the spring may have broken or somehow came out of its attaching point. Obviously be very careful about over-revving the engine, it could result in a broken connecting rod and a hole in the side of your crankcase.

Hi sounds like a carbretta problem, not enough fuel reaching the engine for it to run at higher rev's.
