Start with basic things first, drain the fuel tank and re fill with fresh fuel, remove the spark plug, is it soaked with fuel? if so dry it , put the ignition unit to off, with the plug still out crank the engine a number of times to remove any excess fuel in the bore, check there is a spark at the plug, if yes leave the saw to dry out for a couple of hours, refit the plug and try again, remember to switch the ignition on

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 :

The carburetor might be clogged and needs to be cleaned.

A chainsaw`s carburetor mixes air and fuel to start the internal combustion engine. If fuel has been left in the engine for too long, it can become sticky and clog the carburetor, preventing it from starting. If the clog is minor, clean out the carburetor.

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.
Bad Spark Plugs

If the engine holds compression well, and the fuel system is working correctly, but it still won`t start, that tells us that your car`s spark plugs may not be working. The spark plugs ignite the air/fuel mixture inside the engine`s cylinders. It`s the resulting explosion that actually powers your car.

Trying to start your car without much gas in the tank? This may be the problem! Many cars simply won`t start at all if there is a very low fuel level in the tank, even if there`s enough fuel to drive for a few miles. In general, it`s a bad idea to drive around with an extremely low fuel level in your tank.
A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
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.
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.
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.
The two most common reasons a chainsaw won`t idle are a blocked air filter and an idle screw out of adjustment. Other possible causes include: Dirty Air Filter. Idle Screw out of Adjustment.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.

I have a husqvarna 137 chainsaw. The problem is with the bar oil. When the saw runs oil is flowing but where the rubber corner piece which allows the oil to flow out of appears to be just dripping the oil straight out. It looks like it should fill a small reservoir behind the metal plate and the oil then moves upwards where the chains drags the oil through the oil hole on the bar which is moving outwards as in the top chain on the bar. However the chain-brake area is just getting messy with oil splattering all over and the bar not actually getting oiled. I have fitted a new metal plate to see if the corner of the original was not sealing properly but that has not helped. The bar holes are clean. Any suggestions as I can’t see what it could be?
ANSWER : It’s the rubbers. I had the same problem with my 137 and 141. The rubbers shrink over time and the oil never makes it up the channel. The replacement part is one piece and less prone to leaking than the original 2 piece design.
