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 :

If the spark plug produces a spark and you are still having difficulties starting your chainsaw, it`s time to check the gap. The spark plug gap is an air gap between the ground electrode and the center electrode. If the gap is too small, the spark struggles to ignite the fuel and air mixture.
If your chainsaw still starts and then stops working, check the air filter. Clean or replace the air filter if it is dirty or damaged. Another reason that your chainsaw starts and then stops working could be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.
A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
If your STIHL chainsaw is going to have a problem, it`s likely to be with a worn carburetor, bad spark plugs, loose fuel hoses, or clogged fuel lines. You should also inspect the fuel intake system and ensure that there are no compression issues.
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.

With the choke in the “off” position, pull the engine`s crank cord through again. The engine should start in 1 to 3 pulls. Try it first without using the throttle control—unless recommended by the manufacturer.
What Causes Chain Saw Kickback? There are two circumstances that can cause kickback when using a chain saw. The first occurs when the moving chain at the tip or the nose of the guide bar strikes an object. The second situation is when the wood closes in, pinching the saw chain in the middle of the cut.
Smart Start is one of Husqvarna`s unique technology because when their chainsaws are installed with it, it means it`s extremely easy to start.

Gas tank leak – Husqvarna , No.455 Rancher, 20" Gas – Powered Chainsaw
ANSWER : From weher? between cap?

55 rancher Husqvarna got very hot due to no oil in gas, and will not start again.
ANSWER : The piston rings rely on the oil in the gas to lubricate the cylinder wall. More than likely, the rings are now too small to provide the proper seal for enough compression. It could also have worn the cylinder wall more than the rings, the end result is the same.

You can try to remove the plug, put in about a 1/2 teaspoon of oil into the plug opening, slowly pulll the rope 1 time to let the oil coat the ring & wall & then put the plug back in & try to start it. Use a little extra oil in your gas to provide thicker lubrication. good luck
