How to repair the starter rope in a lawn mower

How to repair the starter rope in a lawn mower

Each time you pull start your mower, the nylon braided wire is rubbed against the round and smooth splint on the side of the starter coil. This constant friction makes the rope wear out and finally break. Since it only takes a few minutes to adapt to a new cable, removing the recoil starter and winding a new rope around the pulley at the first sign of wear, it is easier to replace a frayed rope than to excavate the jammed debris from the pulley des Then the rope fits.

Instructions

1 Loosen the three or four 1/4-inch bolts that hold the starter coil to the motor with a socket wrench, and place the unit in inverted position on your workbench.

2 cut the cable just below the starter handle with a pair of side cutters and unwind the wire around the pulley. Grasp the knot protruding from the pulley flange with a pair of pliers, and pull the worn rope out of the starter motor.

3 Feed a new rope through the starter handle. Tie an eight knot around the end of the cable protruding through the back of the handle and cut the rope about an inch from the knot. Hold the handle with one hand and give the rope a couple of pulls to tighten the knot.

4 Relax the pulley around half a turn counterclockwise against the return spring tension until the flange hole in the pulley lines aligns with the ferrule on the side of the casing. Keep the pulley with your thumb and feed the new cable through the splint and up through the hole in the pulley flange.

5 Tie a single knot on the end of the cable. Pull the protruding rope out of the splint, and give it a couple of pulls to tighten the simple knot on the pulley. The ease of the rope to allow the pulley, to close the clock needles again around half a turn until it stops.

6 cut the cord about 3/8 inches from the knot and seal the end by melting with a lighter or phosphorus to prevent frayinging.

7 Hook a folded paper clip around the rope between the splint and the pulley. Pull the rope up to form a loop between the pulley and the inside edge of the casing, until the handle rests on the side of the casing. Rest the pulley a bit to align the notch on the upper outer edge of the pulley, about an inch before the splint arrives.

8 Insert the end of the rope pulley into the notch on the edge of the pulley at the bottom. Roll the two-turn pulley anti-clockwise against the return spring tension until the rope engaged in the notch is just after the splint. Pull the starter handle to release the rope from the notch; Relieve the tension on the rope to allow the pulley to relax and draw the handle to the side of the casing.

9 Check that the rope has removed the starter handle all the way to the side of the back casing; If there is still some slack, repeat the previous step and the tension of the pulley to the left again, before pulling the free rope from the notch on the side of the pulley; This should point the handle to the bottom against the side of the casing.

10 Attach the starter coil to the motor with the screws removed above, and the test to start the mower to complete the installation.

End-of-season storage : lawn mower

End-of-season storage : lawn mower

To avoid starting problems next season, run the mower until it is cut for lack of fuel. This should remove most fuel from the carburetor and bowl and help prevent all gumming up. To prevent corrosion, allow the mower to cool, remove the spark plug and place a teaspoon of oil through the plug hole. Pull the starter cable a couple of times and replace the plug. Remove all the caked grass from the bottom of the shelf as it can ferment, acidify and eat through the metal over time.

Routine lawn mower maintenance checks during the summer

Routine lawn mower maintenance checks during the summer

•     Check the oil every month or more regularly depending on usage.
•     Remove any grass or leaves from the cooling fins in the stock. Air blown through the flaps through the steering wheel drives the heat away from the engine so it is important that they are not clogged.
•     Sharpen the blade a few times during the season, again depending on use. If you have a small lawn, a single sharpening at the beginning of the year should suffice.
•     Check for loose nuts or screws on wheels or other parts of mower.
•     If possible, drip some light oil from the machine into the control cables for the throttle and the unit. If you do this little by little, it will slide along the wires on the cable sleeves, avoiding corrosion and grip.
•     Try to avoid mowing when wet. Wet grass clippings adhere to the bottom of the platform along with mud and other dirt. This clogs the way to the collection bag and eventually the engine may have difficulty during cutting. After use in these conditions, wash the bottom of the platform with a hose, but try not to put water in the motor and air filter.

Do not attempt to start an engine without the blade! : lawn mower

Do not attempt to start an engine without the blade! : lawn mower

Small motors, such as lawn mowers, usually have an aluminum flywheel, and the additional weight of the blade is actually part of the steering wheel system. If you are familiar with the mechanics (a branch of physics), you will know that this increases the moment of inertia of the system. If the blade is removed, it will be difficult to start the engine due to insufficient turn impulse when pulling on the starter cable.

Throttle and Governor links : lawn mower

Throttle and Governor links : lawn mower

    Verify that the throttle cable is actuating the accelerator plate through the links. These can sometimes be caught or obstructed by small grass or twigs.
    Make sure the governor's linkage does not keep the throttle closed. A governor is a device that regulates the speed of an engine, keeping it constant regardless of the load on the engine. On a lawn mower, two types of governor are used. A system consists of a paddle pivoted at one end and connected to the accelerator plate in the carburetor through a spring and joints. The air is directed from the flaps of the steering wheel to the fin. If the motor slows down (due to long grass), this reduces the air force on the paddle. This allows a spring to open more the throttle, allowing more fuel in the engine, which gives it more power and this increases the speed to compensate. The governor also limits the engine's excess acceleration by closing the throttle when the load is reduced. Another type of governor works by centrifugal force. A spool that can slide on a shaft acts on arms that move more outward as the engine speed increases. The Reel powers the accelerator through links.

    With the air filter removed and the use of a torch, you can determine the position of the choke and choke valves. These are dishes that open or close at the entrance. The outermost plate is the choke that almost completely obstructs the airway when it is turned on during a cold start of the engine. The accelerator plate creates the slightest obstruction with the throttle thoroughly and the regulator binding should not be closed before the engine starts. Verify that the governor can move freely and does not stick.

Smoke is a symptom of a tale : lawn mower

Smoke is a symptom of a tale : lawn mower

The color of the exhaust smoke is a symptom that reveals problems with an engine.

White or blue smoke?

This is caused by the burnt oil in the engine. While a certain amount of oil is consumed and burned under normal circumstances, blue smoke clouds indicate a problem. Old engines emit smoke as the cylinder wears out (motor burnout) and the piston and rings no longer fit as well. Excess oil is added to the cylinder and burned. Fractured piston rings can allow a large amount of oil to enter the cylinder.

The oil in combustion can also be caused by a defective vent that allows the oil to be expelled from the sump and then sucked into the engine through the carburetor (if there is a pipe connecting the vent to the carburetor).

However, another cause is an overloaded sump. On one occasion, my neighbor and his helpful friend decided to fill the lawnmower with oil and, being generous, decided to fill the oil to the edge of the oil filler cap. The result? Thick clouds of white smoke I could see in the distance! Yours really had to save the day and drain some oil from the pruner!

Black smoke?

Black smoke is an indicator of burning too much gas. This can be caused by too rich a mixture (adjust the mixer screw), a defective diaphragm or punctured in the carburetor, a choke that does not open when the engine starts or a dirty air filter.

Engine compression : lawn mower

Engine compression : lawn mower

While fuel and a good spark are essential for starting an engine, good compression is also important. Compression is simply the capacity of the fuel/air vapor to be compressed by the piston into the cylinder (also known as the combustion chamber) before the ignition, without spilling out somewhere due to a bad seal.

Lawn Mower Parts Product

You can get a rough idea of compression by placing your thumb over the hole where the screw is threaded and pulling the starter cable or turning the handwheel if it is easier. You should be able to feel the pressure on your thumb. However, with the spark plug back in place, if the compression is severely compromised, the starter cable will be easy to pull, no resistance.

Bad compression can have several causes:

•     Spark Plug loose. It could be as simple as a loose spark plug, so tighten it. Do not use excessive force when tightening.
•     Defective cylinder Head gasket. The cylinder head is the part of the motor on which the plug is mounted. This is screwed into the cylinder block with the gasket inserted. You may notice burns or soot marks around the edges of the gasket.
•     Bore Wear. Another cause of bad compression is the wear of the orifice, which causes the piston to seal badly in the cylinder. This can happen when an engine reaches old age, or if it has been used without air filter or with little oil.
•     Clogged Open valves: Fire and spit. Another cause of poor compression is an open or poorly seated valve. During the 4-stroke cycle, an inlet valve is opened and allows the air/gas mixture to flow into the cylinder, and an exhaust valve opens to allow the burned gases to be ejected from the cylinder. During the compression stroke, both valves must be closed. Now, if valves do not settle and seal completely due to wear, the accumulation of deposits or the exhaust valve burned during many years of use of the engine, the compression can suffer. Another scenario is if an engine to one of the valves open. If the motor is stored for years without use, what can happen is clogging the valve in this position. Now, normally, a cam shaft opens each valve through rods in contact with the pushers called stems, and a spring returns the valve to the closed position. If the valve becomes clogged, the spring force is not strong enough to return the valve to the closed position. The symptoms of a stuck or worn valve may spit or shoot through the carburetor or the escape while the engine starts or that the Starter cable is actually easy to pull. So the moral of the story is "exercise" machines in storage periodically to prevent this from happening. This can be as simple as gently pull cable starting motor so all move internally. This applies to anything with moving parts, including engines, motors, tools and workshop equipment.

In fact, I experienced a compression problem with my lawn mower this morning, although it's not too old. The cable was easy to pull without resistance so I guess it jammed a valve. After leaving the engine for about an hour, the problem was solved, perhaps because the oil penetrated the lifters or valve stems.

When looking inside the cylinder through the spark plug hole or removing an inspection cap over a compartment (known as a valve hood) that provides access to the pushers, you can see if a valve is opening. Some engines have OHV or higher valves, and can be accessed again by removing an access cover. The valves can be released by spraying WD40 on the valve seat and on the stems. However, this may be beyond the ability of the hobbyist. If it is necessary to remove the cylinder head, when replacing it, the screws must be tightened in a staggered sequence and the bolts should ideally be re-tightened with a torque wrench.

The spit can also be caused by a mixture that fits too thin, which requires the mixing screw to turn to the left to enrich it (see above procedure). Another cause of spitting is a cut-off key, causing the timing to be off and the spark plug to trip at the wrong time.
