The Kohler OHV engine uses a valve adjustment procedure that is different from most engines. The valves on this engine are located in the head, and they are actuated by pushrods. There are two valves per cylinder, and they are opened and closed by a rocker arm.
The valve clearance is the space between the valve and the rocker arm when the valve is closed. The clearance is adjusted by loosening the locknut on the adjustment screw and turning the screw in or out.
- Make sure the engine is off and the spark plug is disconnected
- Remove the valve cover to gain access to the valves
- Adjust the intake valve first by loosening the locknut and turning the adjusting screw clockwise until it is tight
- Adjust the exhaust valve by loosening the locknut and turning the adjusting screw counterclockwise until it is tight
- Replace the valve cover and reconnect the spark plug
How to Adjust Valves on a Kohler Command Engine
If you have a Kohler Command engine, you will need to adjust the valves periodically. This is a relatively easy task, but it is important to do it correctly.
First, remove the valve cover. There are four bolts holding it on, and you will need a socket wrench to remove them. Once the cover is off, you will be able to see the valves. There are two types of valves – intake and exhaust. The intake valves open to let air and fuel into the cylinders, and the exhaust valves open to let exhaust out.
To adjust the valves, you will need to turn the engine over until the piston is at the top of the cylinder. For the intake valves, you will need to turn the engine so that the piston is at the top of the cylinder on the compression stroke.
For the exhaust valves, you will need to turn the engine so that the piston is at the top of the cylinder on the exhaust stroke. Once the piston is in the correct position, you can adjust the valves. The valves should be adjusted so that they are just barely touching the rocker arms.
To do this, use a feeler gauge. Place the feeler gauge between the valve and the rocker arm, and then tighten the adjusting nut until you feel resistance. Once the valves are adjusted, you can replace the valve cover and start the engine.

How do you adjust the valves on a OHV small engine?
If your small engine has overhead valves (OHV), you will need to adjust the valves periodically to ensure peak performance. The specific interval will vary depending on the make and model of your engine, but it is typically every 50 hours of use. To adjust the valves, you will need to remove the valve cover(s) and inspect the clearance between the valves and the rocker arms.
The clearance should be between 0.004 and 0.006 inches. If it is outside of this range, you will need to adjust the valves. To adjust the valves, you will need to loosen the lock nut on the adjusting screw and then turn the adjusting screw until the desired clearance is achieved.
Once the clearance is set, tighten the lock nut and replace the valve cover(s).
How do I fix my Kohler engine surging?
If your Kohler engine is surging, there are a few things you can check to try to fix the problem. First, check the air filter and make sure it is clean. If it is dirty, replace it with a new one.
Next, check the spark plug and make sure it is clean and in good condition. If it is dirty or worn, replace it with a new one. Finally, check the fuel filter and make sure it is clean.
If it is dirty, replace it with a new one. These are the most common causes of engine surging and should fix the problem.
What are valve clearances?
Valve clearances are the small gaps between the tips of the valves and the contact surfaces of the rocker arms or valve lifters. These clearance gaps are essential for proper valve operation, and they are adjusted by the use of shims. Valve clearance is important because it ensures that the valves open and close at the proper times.
If the clearance is too small, the valves will not open far enough and will not allow enough air and fuel into the cylinders. If the clearance is too large, the valves will bounce off the rocker arms and will not seal properly, resulting in reduced power and fuel economy. Valve clearance is typically checked and adjusted during a routine engine tune-up.
The procedure is as follows:
1. Remove the rocker arm covers.
2. Using a feeler gauge, measure the clearance between the valve tip and the rocker arm.
3. If the clearance is outside of the specified range, remove the shims and measure their thickness.
4. Install new shims of the appropriate thickness to achieve the proper clearance.
5. Re-install the rocker arm covers.
What are symptoms of valves out of adjustment?
Valves that are out of adjustment can cause a number of symptoms in your car. These can range from a loss of power to strange noises coming from the engine. If you notice any of these symptoms, it’s important to get your car to a mechanic as soon as possible to have the valves checked and adjusted.
One of the most common symptoms of valves that are out of adjustment is a loss of power. If your car doesn’t seem to be running as well as it used to, or if it’s having trouble accelerating, this could be a sign that the valves are out of adjustment. Another symptom to watch for is strange noises coming from the engine.
If you hear ticking, clicking, or knocking sounds, it’s possible that the valves are the cause. These noises can indicate that the valves are not opening and closing properly, which can lead to engine damage. If you notice any of these symptoms, don’t ignore them.
Get your car to a mechanic as soon as possible so that the valves can be checked and adjusted. Ignoring the problem could lead to serious engine damage.
If you have a Kohler OHV engine, you may need to adjust the valves from time to time. This is a relatively simple process, but it’s important to do it correctly. Just, follow the simple steps in the above and complete your work easily.
