Steps to Clean Lawnmower Carburetor:

Suppose you’re looking to service the carburetor without removing it. In that case, follow the steps below that guide you thoroughly.

● 1. Analyze the situation before cleaning:

You should know why you are looking to clean your lawnmower’s carburetor in the first place. The primary function is to supply a correct mixture of air and gasoline to the engine for combustion. The engine produces power.

Over time, dust settlements develop within carburetor jets that can eventually clog these jets. Despite the air filter, your carburetor witnesses likely blocking issues after a specific time, and your engine problems indicate that.

– Step 1: Do an initial checkup:

If your engine isn’t starting correctly, it just stalls after starting, or it’s not producing enough power. Then, it means there are debris deposits in your engine’s carburetor. Thus, it is high time to service your carburetor.

If you’re not a proper mechanic, we recommend avoiding disassembling the entire carburetor and cleaning it without completely removing it. For this purpose, we have summarized the process in easy steps for you.

– Step 2: Record your steps:

Now that you want to disassemble the parts, taking the mower’s initial pictures is better. These pictures give you a better idea of where to put the parts during their assembly if you forget which thing goes where.

● 2. Expose the carburetor by removing and cleaning the outer components:

This step is where the disassembly begins. You can refer to the full instructions below:

– Step 1: Remove the air filter:

The air filter is situated at the exterior of the mower adjacent to the fuel tank. It usually comes off in most mowers. For that, you might need a screwdriver to remove the screws securing the filter.

Now that it has come off, it might be a good idea to clean it using soap and water. A dirty air filter might be one of the reasons that led to the carburetor’s clogging in the first place.

– Step 2: Remove the fuel lines:

Now that your carburetor is visible after removing the air filter, you should detach the fuel lines, leading to it using nose pliers. Keep a plastic bottle in which you can insert the fuel line so that the whole of the fuel drains into it.

Note that the entire fuel in your tank needs to be disposed of properly since it is probably the primary source of the dirt in the first place. A yellowish fuel means that it has become stale.

– Step 3: Unscrew the jets:

Afterward, use a wrench to unscrew the bolt underneath your carburetor bowl (which also has a jet). You should remove the bowl as the nut securing it has come off. Then, slowly pull your gaskets and check if they are in good condition.

Assess your float by pressing it. If it gives a clicking sound, the needle is going precisely into its original position, which is how it needs to be. Place the jets and the bowl separately so that they can be cleaned.

● 3. Clean the components:

The parts that have been removed are cleaned in this step.

– Step 1: Cleaning the jets:

The nut that secures the bowl is also the main jet with a tiny hole for air passage. This jet is one of the most common sites for debris buildup. There are many ways of cleaning it. You can use a thin metal wire and pass it through the jet to remove dirt.

Or you can use an Aerosol cleaner for carburetor cleaning and spray some of it onto the jet. Also, if you see some flakes on the nut’s side, it is always better to remove them using sandpaper.

– Step 2: Cleaning the bowl:

Before cleaning the bowl, assess whether it can be reused. If scales or rusts have developed inside to a great degree, then it’s a good idea to buy a new one and replace it altogether. If you want to clean it, you can put some carburetor cleaner and scrub it afterward with sandpaper.

– Step 3: Spray the interior with the cleaner:

It would help if you used the aerosol spray to effectively clean the carburetor’s interior connected to the lawnmower body. It might also be helpful to use a compressed air gun for spraying, eventually removing all the dust that developed over time.

Pouring the carburetor cleaner at the engine’s center while running would be best. Due to the running engine, liquid flows entirely through the jets, leaving behind no clogging. However, it would help if you never touched the carburetor when the engine was on.

● 4. Reassembly of the parts:

Now that your cleaning is complete, it is high time to refer to the pictures you took earlier and figure out which part fits where. First, you should assemble the carburetor parts by securing the jets and renewing the gaskets where needed.

Screw the bowl nut tightly and use a dry rag to clean it from the outside gently. Connect the fuel lines back to the carburetor and secure them in place by tightening their claps.

Now, put the air filter and the fuel tank back into their original positions and screw them tightly. Your carburetor cleaning is now complete. You can add fresh fuel and start the engine to check if your initial problems are solved.

Related Questions:

● 1. Can you clean a lawnmower carburetor without removing it?

You can clean a carburetor without disassembling it completely. During this cleaning, only the bowl nut and the bowl come off and are washed separately.

The remaining unit that hasn’t been disassembled should be cleaned with an aerosol cleaner. For carburetor cleaning, you should first determine the age of your component to decide if cleaning solves the problem.

If your carburetor is old enough and has been serviced quite frequently in the past, then we recommend that you replace it with a new unit. If it’s not old, you can always clean it to remove the dirt or debris built up over time.

● 2. Where do you spray carburetor cleaner on a lawnmower?

You are highly preferred to spray the carb cleaner when the engine is running. To clean, you should place the cleaner’s tip at the center of the carburetor at the base of its throat and spray the liquid.

Doing this on the running engine allows the cleaner to flow thoroughly into the jets and the holes, thereby cleaning any sludge deposits.

● 3. What can I use instead of carburetor cleaner?

If a carburetor cleaner is unavailable, a brake cleaner is a reasonably good substitute. It is compatible with carburetors and can dissolve grease and sludge buildups. It is made up of chemicals that evaporate after drying, thus leaving behind no residue.

● 4. How do you know if your carburetor needs cleaning?

If you face either one of these four below cases with your engine, then it is a sign showing your carburetor needs servicing:

– The engine does not start at all

If the engine does not start at all, it is a sign that the carburetor is so dirty that the air-fuel charge cannot reach the engine.

– The engine is running lean

Engine running lean is when the air-fuel mixture is disturbed (increased mainly). Typically, the air ratio to fuel ranges from 12:1 to 15:1. If too much air is fed to the engine or insufficient fuel is provided, it produces a popping sound at the air inlet. This condition happens when the fuel jets are clogged.

– The engine is running rich

Engine running rich is the opposite of the above case. In this case, excessive fuel is being supplied to the engine. This situation causes black smoke to rise from the exhaust.

– The engine is flooding

Engine flooding occurs when the needle valve in the bowl is clogged, due to which it does not, and the fuel floods the carburetor. This condition eventually disturbs the air-fuel ratio, thus indicating the need for carburetor cleaning.

Remarks

Lawnmowers need maintenance as frequently as any other machine. Now, since they are subjected more to dirt and debris, it is quite possible that clogging can result in various types of problems. To clean a lawn mower, you’ll need to remove the casing.
