How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

For best results and performance, use HUSQVARNA two-stroke oil, which is specially formulated for our two-stroke engines. Mixture 1:50 (2%).
The correct mixing ratio for your Husqvarna is detailed in the warranty handbook. As a general guide, a fuel / oil ratio of 50:1 is recommended in Husqvarna products up to and including 75cc. In certain heavy use applications, models above 75cc may be run on a mix of 33:1.
Husqvarna two stroke engines are designed to run on clean, fresh, unleaded petrol. A fuel / oil ratio of 50:1 is recommended for all Husqvarna 2-stroke products. Also consider; 50:1 (2%) fuel / oil mix ratio is recommended with the use of genuine Husqvarna two-stroke oil for best performance.
The fuel tank capacity of Husqvarna Svartpilen 125 is 9.5 Liters.
Be sure to use 89 octane or higher unleaded fuel. For best results, use Husqvarna brand two-stroke engine oil that if FD certified. Always mix gasoline and oil in a clean fuel container, not in the chainsaw`s fuel tank.
This engine model requires a 25 thousandths of an inch gap.
However you choose to use your leaf blower, it will require periodic and annual maintenance to include cleaning or replacing your unit`s fuel filter as they do tend to get clogged over time. The most common reason for a fuel filter getting clogged is storing a leaf blower for an extended period with gas in the tank.
The stoichiometric mixture for a gasoline engine is the ideal ratio of air to fuel that burns all fuel with no excess air. For gasoline fuel, the stoichiometric air–fuel mixture is about 14.7:1 i.e. for every one gram of fuel, 14.7 grams of air are required.
If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.
If you`re using a different brand of 2-Stroke oil, you`ll need to mix at 25:1 (40mls oil per 1 litre fuel). Petrol has limited shelf life (as low as 30 days), so always mix with fresh regular unleaded purchased from a reputable large volume fuel supplier.
Husqvarna 125 WR Specs

The engine produces a maximum peak output power of 10.00 HP (7.3 kW) @ 8500 RPM and a maximum torque of .

Any octane of gas available at your local gas station should work fine in your lawnmower, as long as you avoid the diesel section. High octanes won`t necessarily improve your lawnmower`s performance, but they won`t hurt the engine.
Can I Use 90 Octane In My Lawn Mower? A majority of lawn mowers and four-stroke engines do not need premium gas or a high octane rating like 93 octane gasoline. The majority of mowers will work fine with an octane rating of 87-90.
The gap setting is different for each vehicle but most are somewhere between 0.028″ and . 060″. Consult the owner`s manual or Champion ® catalog to find the recommended setting for the vehicle you`re working on.
Correct Gap

The gap between the spark plug`s center electrode and outer electrode should be set at 0.02 inch, or 0.5 millimeter, for most Husqvarna trimmer models. On some newer models, the company recommends a slightly larger gap of 0.024 inch, or 0.6 millimeter.

To prevent the machine ingesting enough contaminants to clog up or wear down the engine, most gas leaf blowers have air filters. In order to ensure they perform their function of filtering the air before it reaches the carburetor, it is important you keep them clean. The first question you need to ask yourself is this.
A clogged carburetor is most commonly caused by leaving fuel in the leaf blower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.
Find the adjustment screws on the front of the carburetor.

There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.

E10 can be used in all current Husqvarna equipment, however, we recommend using at least 89-octane E10 gasoline, which is the mid-grade between regular and premium gasoline.
Without your fuel filter, dirt, contaminants, and other gunk could make its way to your engine and cause all sorts of trouble. The fuel filter is an active participant in delivering clean fuel to the engine while protecting fuel injectors.
Well as long as the lack of that fuel filter doesn`t cause leaking at the inlet connection, then yes it will run fine ….
Fuel and Air Intake

Filters for carbureted engines may be located at the inlet of the carburetor or inline. Filters for carbureted engines do not need to withstand the same pressures as those for fuel-injected engines.

Choosing the right unleaded fuel & right two-stroke oil

That`s why the best bet is to always go with Husqvarna`s premium lubricants including our premixed XP+ fuel and oil. If not using a premixed fuel and oil blend, you should always use unleaded ethanol-free gas for your outdoor power equipment.

For best results and performance, use HUSQVARNA two-stroke oil, which is specially formulated for our two-stroke engines. Mixture 1:50 (2%).
