5 Most Common Problems of Kawasaki FR651V and their solutions:
The users’ pain as a result of the malfunctioning is pretty unpleasant. Occasionally, the motor may start but will run at a very slow speed, which is really irritating.
Let’s have a look at the difficulties and possible remedies:
1. Low spark
Spark loss is caused by anything that prevents coil voltage from leaping the electrode gap at the end of the spark plug. This includes spark plugs that are worn, fouled, or damaged, as well as defective plug wires and a fractured distributor cover.
To fix these problems, you must first understand why they exist.
The electrodes of a spark plug will not ignite properly if they are worn thin, coated with combustion deposits, or moist. If the plug has been in use for a long time, the electrodes may simply have worn out. Another reason is if you see a thick coating of black carbon deposits on your engine, it means the carburetor mixture is too rich and your engine may be smoking.
You may feel powerless in this situation since you are unsure of what to do. This article may be of use to you in these instances. The entire handbook can be found below:
First of all, you must identify the problem’s source.
However, if other elements of the engine aren’t working, you can usually find out what’s wrong by looking at the plug. Excessive dry deposits or electrode wear usually indicates a problem with the combustion chamber’s fuel-to-air ratio, while oily deposits could suggest a cracked engine seal.
The remedy is to replace the spark plug. Because the engine cannot start when these sparking plugs cannot spark effectively. In this case, you should replace or repair the spark plugs.
2. Charging system failure
You finally get around to mowing your lawn, only to discover that your lawn mower battery is dead. It’s inconvenient to have to take extra steps to start your mower, such as charging or replacing the battery.
When your battery cables are loose or your connections are unclean or rusted, your lawn mower battery can continue to drain. Your battery can also be drained by a broken charging system, a bad battery, or leaving the ignition key in the on position.
So, the problem can be solved by following the manuals below:
The charging system failure causes Kawasaki FR651V engine difficulties. The simple fixture is to use a hot wire from the B+ terminal of the battery and the voltage must be correct for your specific battery if you can’t use a greater voltage at the B+ terminal. The voltage at your B+ terminal will always be lower than the voltage at the main battery.
3. Fuel line blockage
Fully working fuel lines have only one purpose: to transmit a precise amount of fuel from your fuel tank to your engine. You’ll notice a lack of fuel flow or uneven fuel flow to your engine if your fuel line is damaged.
If your gasoline line is nearing the end of its usable life, it’s probable that it’s clogged. Even with the best fuels, debris will accumulate in your fuel system over time. Dirt in the engine or faults in the gasoline might cause gunk to form. A clogged fuel line can cause sputtering or even engine failure in a running engine.
Your solenoid is unable to supply fuel to the carburetor when your fuel line is obstructed, preventing the engine from starting.
Allow fuel to flow by opening the pipe. After you’ve opened the block, reconnect the pipe.
Another simple method is to use compressed air from the fuel tank. It will also help you get rid of the stumbling block.
Most importantly, do not forget to clean down the gasoline tank cap to prevent blockage.
4. Low compression
Kawasaki FR651V has a combustion engine quite similar to those seen in automobiles. Compression is the pressure that builds up inside the piston chamber as a mixture of fuel and air is compressed and a spark is supplied. The resulting explosion forces the piston is outward, turning the crankshaft.
Compression loss can occur when your pistons wear out, the seals around your pistons wear out or a push rod bends or breaks. The problem may be fixed by following the manuals below:
First of all, compression may seep out of the hole created by a loose plug. Restart the engine after completely tightening the spark plug with your ratchet set.
On the next step, examine the bolts that secure the cylinder head’s top. If these nuts become loose, the cylinder’s compression might escape. Tighten any loose bolts with your ratchet set, then restart the engine.
Next, remove the cylinder head cover and look for any damaged pieces or bends in the push rods and valve lifters. It is necessary to repair any broken or damaged parts.
After that determine if your low compression is due to worn valves or worn piston rings. Grip the crankshaft with your wrench while the tester is in place and rotate it. Compare the tester gauge results to the compression range recommended by your lawnmower manufacturer. If the oil fixes the compression problem, the fault is in the rings. If it doesn’t, a worn valve might be the problem.
Despite of these solutions, it is better to replace the defective pieces right away.
Overheating is commonly caused by too much ethanol in the gas, is indicated by thinned electrodes. If your plug has moist, oily deposits, it’s time to service your mower because oil is seeping into the combustion chamber where it shouldn’t be. Furthermore, when clogging occurs, delivering fuel becomes more difficult.
You can solve this difficulty by utilizing high-quality gasoline, which is suitable for this engine. Make certain your gasoline isn’t contaminated with water.
Also make sure to remove all the clogs in order to allow the fuel to flow freely.
