Common Problems With Kawasaki FR691V and Their Possible Solutions

You may face a Kawasaki fr691v problem when you use it for a few months but don’t worry about these minor issues. Some of the most common problems and their solutions are given below:

1. Kawasaki FR691V Carburetor Issues

It may cut out if you keep mowing with your Kawasaki FR691V engine. For this, you should pull the throttle so that it keeps going. The engine can also start limping and return to the garage, but it’s a common issue. However, it will work for a few minutes before you use it again for the subsequent cutting. Give it some time for rest. It will function in the usual way. 

But do it only for a few minutes. It may happen due to the float, as it can get stuck and shut the carburetor. The solution is straightforward, and you can do it by yourself.

Solution of the problem

The solution is straightforward only replace the carburetor and clean the fuel filter. If the problem is there and nothing is happening, check the fuel solenoid inside the carburetor. The solenoid is the component that can create a problem with the throttle. The solenoid can create other problems, like blocking the main jet when it is off, losing the voltage, and simply overheating due to the faulty coil. 

The best option is to take it out, plug it in from the mounting hole, and run it, but you may need help. Whereas, another reason for this problem is that the needle valve channel of a new carburetor can contain oil line dust or junk. To check this problem, remove the needle valve and blow it from any valve opening towards the fuel recess.

Use a clean cloth to wipe out the tiny particles that resemble hair. Only old fuel lines flake the fuel tank inside due to the ethanol.

2. Kawasaki FR691V Starter Issue

Another common problem of the Kawasaki engine is the starter issue. The causes of these starter problems are failure of components, battery build-up, overheating, and many more. The symptom of this issue is that the mower can turn but doesn’t start, or it may become hard to start it or also cannot crank.

To check the reasons, open the hood and look at a few things. For the rocker bracket bolt, see if the bolt is in place or if it has yet to come out from the hole. The push-rod, rod can also bend due to the extreme tightness of other valves.

Solution of the problem

First, check the battery connections and safety switch of the starter solenoid. If all of the parts are good and at their place, then ensure that the valve is adjusted correctly. Change the push-rod if it got bent and check that all of the rocker supports are at their place in the head. Also, ensure that the replacement push-rod is correctly fixed at the correct location.

For ease, you can make an index mark on the head and the block. And always check the spot if it stops at the same spot. The coil-bound valve may result from improper setting of the push-rod, which the starter cannot overcome. However, if the performance is the same, take the Kawasaki 691v to the shop or dealer.

3. Kawasaki FR691V Engine Backfiring

One of the most common Kawasaki fr691v problems is the backfiring of the engine. It is due to the load, and a common term used for this problem is “popping under load.” But this problem will not come across when you off the blade from the machine. The backfiring indicates that the problem takes place due to the load. However, you may also face this problem while mowing, and the engine will begin to backfire and die.

Moreover, when you open the throttle and choke to half, the Kawasaki engine will rev higher and not run longer. Due to this, it cannot run smoothly and produces heavy smoke in the black when it is open or closed.

Solution of the problem

The cause of backfiring is the lack of fuel and the carburetor issues. To resolve this issue, drain some fuel from the tank and refill it with quality fuel. Then check the carburetor to see if the air filter is good and works well. Check all the connections, plugs, and wires thoroughly. The 80% account of water in the gas will stop the pooping. 

Mostly the backfiring and stooping happens because the gas becomes old for more than 30 days. When the amount of water exceeds the gas, the pooping will stop when you try to crack up. Half choking may help suck out the water and do all things at a better point.

4. Kawasaki FR691V Blown Head Gasket

The blown head gasket includes smoking, lack of compression, and backfiring. Moreover, milky fuel is also noticeable in this scenario. Whenever you start the blades, it starts backfiring and starts to blow smoke. At the start, it remains slow but, with time, breaks out vigorously.

When you have the problem of blow head gasket, you can notice white smoke. It indicates that it may have a crack wrap head or both. In this situation, the cylinders can also produce a hissing sound.

Solution of the problem

When you start the engine, pull the dipstick after a few minutes of running and then turn it off. Check out the dipstick for milky oil because the rising oil confirms a blowhead gasket. Verify that the plugs are clean after removing the blades.

If the problem remains, it’s time to replace the head gasket. For this, take your Kawasaki fr691v to the respective dealership.

5. Kawasaki FR691V Fuel Problems

It is easy to figure out the fuel problems, and you can spot it from fuel consumption, overheating crankcases filled with gasoline, and creepy noise. All of these problems are due to oil leakage, cracked fuel tanks, clogged airways, clogged fuel filters, and interruptions during mowing.

Solution of the problem

It would help if you replaced the fuel tank instead of repairing it because any damage or crack in the fuel line may cause an accident. Also, check that the fuel is up to the level and avoid over-fueling. Try to work in short intervals and avoid continuous use so the mower will not overheat.

Clean the fuel tank, it will help to increase the lifespan of your Kawasaki fr691v. You can solve these fuel pump problems with these steps, and all situations are associated.

When it comes to Kawasaki engines, they have worked for almost half a century and provide their services as supportive of Kawasaki Heavy Industries. This type of longevity is possible due to the high-quality products they produce for the broad market, and Kawasaki does it passionately. This small engine subsidiary provides its service worldwide and takes over the primary marketplace.

The reason for the popularity of Kawasaki engines depends on various factors: power output, environment friendliness, fuel economy, and versatility. Kawasaki also makes their name due to the reliable and durable build quality that will give an extended lifespan to the engine. It also depends on the use and the maintenance.

However, the Kawasaki motors have a life span of about 10 years or more, which is more than enough for this quality engine. They also become famous due to hardly needing common fixes or repairs. Regarding warranty terms, they provide a 3-year warranty for its 4-cycle engines, which means about 3,500 hours of runtime with service interval marks of about 50 hours.

We recommend keeping it safe and checking after short intervals for the inspection of motors, especially after a long period of storage. The Kawasaki engines provide a service schedule chart with details for the service and the intervals. This guide chart will also provide information about the best oil for your motor.

Try to place your machines in a cool and dry place whenever you want to store them for a long interval of time because storage can impact your engine’s lifespan. You can also use canvas fabric to protect it against dust.
