3. Carburetor Problem
A complex piece of machinery with several moving components is the carburetor. Internal combustion engines must have carburetors because they combine the air and fuel to guarantee optimal combustion.
They may run into many problems that impair engine performance.
The buildup of debris, varnish, or silt in the fuel system can cause the blockage of the carburetor or unclean, which is a typical issue.
To address this, it is crucial to regularly clean and maintain it, ensuring the passages and jets remain clear.

4. Vibrations
The Kawasaki FX801V engine, while generally regarded for its excellent performance, has occasional vibrations-related issues.
Some users have reported Kawasaki Fx801v problems like vibrations that can be disruptive during operation.
Various factors can cause these vibrations, including imbalances in the crankshaft, worn-out or damaged engine components, improper installation, or irregular maintenance practices.
It is crucial to address vibrations promptly, as they can lead to increased wear and tear on the engine and potentially affect overall performance.
Solutions
- Examine the motor mounts on the engine, and replace them if necessary.
- Balance the flywheel appropriately, and don’t allow it to break. If required, have the flywheel balanced or changed by a professional.
- If the engine’s air filter is dirty, check it and clean it or replace it since a dirty filter might result in vibrations.
- Because a shortage of fuel flow might result in vibrations, check the fuel filter in the engine and clean it or replace it if it’s filthy or blocked.
- As a malfunctioning spark plug might create vibrations and ensures a proper gap.
5. Hard starting issue
The hard starting issue in the Kawasaki FX801V engine refers to difficulties encountered when starting the engine.
Users may experience a delay or resistance when attempting to start the engine, requiring more effort or multiple attempts before it successfully starts.
Several factors can contribute to this problem. Fuel-related problems, including a clogged fuel filter or a broken fuel pump, are one potential cause that might lead to inadequate fuel being delivered to the engine during startup.
Another potential factor is an ignition problem, such as a faulty spark plug or ignition coil, which can hinder the ignition process and make starting the engine challenging.
Solutions
- If the gasoline filter seems to be dusty or blocked, replace it.
- Check to see sure there is enough gasoline in the tank and that it is fresh.
- Remove any obstructions or debris from the carburetor that could obstruct fuel flow.
- As a weak battery might result in a hard start, so charge it properly and make the excellent shape.
6. Faulty Anti-Tilt switch
Certain Kawasaki motor models feature anti-tilt switches on the motor itself. These are meant to ensure the mower doesn’t continue to run if the engine is angled dangerously, which might lead to tripping. It functions as a kill switch if the maximum tilt reaches.
These sensors, which are occasionally mercury-filled and occasionally driven by electricity, might fail and cause the engine to shut down.
It may also make the engine incapable of operating on even the slightest inclines.
Solutions
The engine may be checked to verify if it runs properly by briefly cutting the ground wire of this switch. Once the problem has been located, a new switch has to be installed for a long-term fix.
Some mower owners may do it skilled at fixing tiny issues with their mowers, but others who need to learn more about mower electrical systems should seek the help of a small engine expert.
7. Bad Coils Problem
As often known, the beginning coil transfers power from the battery, where it is stored, to the sparkplug, where it is utilized to power the engine.
The component costs only $15 to $25, yet your mower needs to function. This component develops a problem that may prevent the engine from starting immediately.
Solution
Replacing a damaged coil is the primary remedy. A capable DIY or landscaping expert can complete it. But if you need help accomplishing this, a qualified small engine specialist is your best bet.
