Honda mower starts then dies. When your mower stops or starts then dies in the middle of a job, it can leave you drained because, well, it’s hot out there and who wants to be working under the sum.
Don’t be worried if this has ever happened to you or someone you know. We’re going to discuss the causes behind the start-then-die issue and how to resolve each one of them.
When your mower dies right in the middle of a job, it can seem like you’re sick, but this issue is more common than many would like to believe and even simpler as a fix than what most might expect.
Let’s take a look at why certain things happen on a regular basis when dealing with these sorts of issues along with ways that they can be dealt with so they don’t affect future use in the near future!
Honda mower starts then dies
If your honda lawn mower starts, runs briefly, then dies there are 4 possible causes: Your carburetor is dirty or clogged, Your gasoline has gone bad, Your spark plugs may need replacing, or You have too much oil in the tank.
A Clogged Carburetor is no laughing matter. A clogged carburetor can cause a variety of different ailments, and the source of the problem is usually something rather simple.
If your lawnmower has trouble starting, chances are that you need to clean out your carburetor.
You may have left fuel in the gas tank for too long where some of the lighter fuel penetrates through and evaporates whilst the heavier substance (usual ethanol) sticks to the walls of the tank and over time, hardens, eventually obstructing all available pathways for air and fuel flow through.
A choke is a metal flap that blocks a carburetor’s air intake, providing extra fuel to start an engine in the correct way. A cold engine will stall when getting more fuel instead of more gas.
It’s important to check the choke during use, look for signs that it stays open when the engine warms up and starts easily. Check if the choke moves freely or if it sticks and becomes unable to open fully because then it won’t work as designed!
You can test its operation by removing your air filter and gauging that depends on your mower model and features.
Problem with Fuel Bowl
All carburetors have bowls that duct containing a fuel supply at the bottom of the air filter. The bowl is commonly found on the right side of some lawnmower engines and resembles a syringe.
It is fuel cap protected unless opened by an amount of gas at which time it will vent slightly depending on your mower’s model.
Cleaning the bowl should ease any gas-related troubleshooting issues and it’s necessary to check regularly for clogged vents or sediment which would otherwise restrict proper airflow (and in more extreme cases hinder your engine performance.)
Spark Plug Issue
Inspect the spark plug for signs of damage or wear.
Replace the spark plug if the porcelain insulator is cracked, the electrodes are burned away or damaged, or if there is heavy carbon buildup at the electrode.
Use a spark plug tester to determine if a spark plug is defective. The tester’s terminals should spark strongly when you crank it. If not replaced, it could cause engine damage.
