Honda Small Engine Troubleshooting. Honda makes a number of products that include motorcycles, jets, cars as well as lawnmowers, and weed trimmers. Aside from making these products for individual use.
Honda also manufactures small outboard marine engines for boats and yachts but the principle behind them remains the same.
When your small engine is struggling or not working at all you can conduct tests on the basic functions to figure out what is wrong. You will need household tools along with replaced parts in order to put your Honda small engine back together again.
Honda Small Engine Troubleshooting
Below we discuss some problems with Honda’s small engines and how to troubleshoot them.
Honda Small Engine Fails To Run
The fuel filter may have become clogged. While the most common problem of a clogged fuel filter has to do with the old fuel being left in the vehicle, there are other causes as well.
As time passes, some of the ingredients within the fuel evaporate, leaving behind a thicker substance that will then begin to clog up the intake system.
If this is what’s been happening to your vehicle, it can cause interference upon running and you might notice that your engine is suddenly stalling or misfiring. If you’ve discovered this problem, take out all of the old gas from your tank and replace whatever parts were damaged when it got clogged.
Inspect the spark plug’s porcelain insulator for signs of damage or wear. If it is cracked, an electrode is blackened or burned away, or there is noticed a buildup of carbon at the electrode, replace the spark plug.
To determine if a spark plug is bad, use a diagnostic tool to check if there are any defective parts in this simple yet vital engine part.
The diagnostic tool should show a strong spark between its electrodes when trying to check for a faulty spark plug.
If there is no spark, this indicates that the old car part needs replacing as it definitely wouldn’t be able to operate properly otherwise.
Honda Small Engine Will Not Start
An ignition coil sends voltage to the spark plugs while the engine is running. If there’s a problem with one of your ignition coils, start by checking your spark plugs and make sure they are clean and in working condition.
If you have confirmed that your spark plugs are in good shape, use an ignition coil tester to test your visual inspection if the spark doesn’t light up the bulb in the tester it means you could have defective ignition coils and should replace them right away before they cause problems.
The flywheel key might have broken in half. The flywheel key is a small metal piece that fits into the crankshaft and engages with the flywheel.
If the engine stops suddenly, the flywheel key can tear or break in half to prevent damage to the engine.
To determine if the flywheel key is fractured, remove the flywheel from the car and inspect your fuel injection system for any signs of cracks or tears.
If you do find any signs of damage, replace it as soon as possible as this could lead to further issues down the line.
Honda Small Engine Leaks Gasoline
The primer bulb may be spurting gas. The rubber inside the primer bulb can dry out and crack over time, causing it to release gas.
Make sure the primer bulb is seated correctly in its gas cap. If that doesn’t work, try using a new primer bulb or have your paint system inspected at an authorized retailer and repair shop.
One or more of the fuel lines may have a leak so it’s best to check for cracks in all three. If any of the fuel lines are cracked or dry get them replaced by someone you trust. If a line is too damaged, don’t repair–replace.
Honda Small Engine Battery Drains Constantly
To determine if the alternator is defective, first test the system voltage using a multimeter. If the reading is below 13.8-volts, then inspect any fuses and wiring before proceeding further with the diagnosis.
If the fuse checks out and the wiring tests good, replace the alternator.
The alternator and voltage regulator must work properly in order to charge the battery.
Though both parts of the equation are crucial, you’ll find that most engine troubles are caused by faulty voltage regulators rather than anything else.
