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. A clogged carburetor is often caused by leaving fuel in the chainsaw 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 cause the chainsaw engine to stall.
A Poulan Pro chain saw engine needs air as well as fuel in order to produce the proper combustion for firing. An air filter that is dirty has clogged passages which restrict the amount of air that can enter the carburetor. As a result, the fuel-and-air mixture may be too rich, resulting in starting difficulties.
If the chainsaw won`t start, or starts and then stops and you find the spark plug wet with fuel mixture, it means that the engine is flooded (you will probably smell petrol). It happens when too much fuel enters the combustion chamber, possibly because you have pressed the primer many times.
How long the chainsaw runs before dying depends on how badly clogged the air filter is. In the case that your chainsaw runs for a while, then dies, it may be possible to simply clean the air filter to correct this symptom. However, a damaged air filter should be replaced.

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 cause the chainsaw engine to stall.

A: The spark plug gap on all products is . 025-inch.
1. Dull chain and or improper lubrication to the bar and chain, sharpen and or clean the bars oil holes. 2. Air filter and fuel filter for restrictions and contamination, clean or replace as needed.
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.
There are many factors that can stop your chainsaw from running, including a bad spark plug or dirty air filter. There are simple problems: a broken fuel line, bad fuel, wrongly calibrated high-low adjustment screw. Also, more complex issues like a damaged carburettor or an engine compression problem.

This method involves looking at the base of the spark plug insulator (white part of the plug) for a slight coloring on the insulator just above where the insulator comes through the steel case. If the mixture is too lean, it will leave no color, while a rich mixture will cause the fuel ring to become more prominent.
The letters on the screws represent High (H), Low (L) and Idle (T). The H screw regulates the Air/Fuel mix during high RPMs, while the L Screw does the same during low RPMs. The T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed.
Yes, Poulan chainsaws are good. In fact, one of its models, the Poulan 306A Chainsaw, was the chainsaw used by Leatherface in the original Texas Chainsaw Massacre movie.
A clogged carburetor is most commonly caused by leaving fuel in the lawn mower 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 cause the engine to stall.
There may be old or bad fuel in the carburetor float bowl. 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 make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
The chain may not have the proper amount of tension. If the adjustment screw is too loose, the chain may not make good contact with the wood. If the chain is too tight, the chain may not rotate at the proper speed, causing the chain not to cut properly. To adjust the chain, tighten or loosen the adjustment screw.
With a firm grip (i.e. left hand on top handle and foot through rear handle) pull the starter cord 3–4 times, or until you hear the engine `fire`. NOTE: Do not pull starter cord more the 3–4 times while on full choke to avoid engine flooding.
Many chainsaw models can be started in what is known as `half-throttle` position. In this position, the chain can rotate – if the chain brake is not activated. There are two safe positions to start your chainsaw: on the ground, or with the saw between your legs.
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
The chain tension may be too tight.

Easy fix, just loosen the bar-retaining nuts and rotate the tensioning screw counterclockwise to the correct tension. Then tighten the nuts back up.

Dirty Carburetor (air+fuel)

If fuel sits in the system for too long, the carburetor (and the engine and fuel lines) can become sticky and clog. Remove the air filter and spray the carburetor with carb cleaner—an aerosolized acetone spray made to remove the gunk.

I prime my tecumseh engine three times as stated. The lawn mower still will not start. How do I investigate to figure out what is wrong? I have taken it to a repair man twice. After I get it back it will start the first couple of times that I try it. Then it goes back to its history of not starting when I prime it 3 times. Sometimes I can prime it 7-9 times and it might start. Sometimes if I prime it 30-40 times it might start the next day.
ANSWER : This sounds like a fuel delivery problem. Maybe remove the carb and tear it down and then soak it overnight in a cleaner after removing all the moving parts…not real hard normally…then let dry and reassemble…If this doesn’t improve the fuel delivery problem, maybe get another carb for it….Make sure the air filter is not plugged up, blocking air flow to the carb itself..just something to make sure of at first.

Does not run, will start with starting fluid – Mantis 2-Cycle Tiller
ANSWER : You should never use starting fluid on this model.

Add a couple of ounces of 100% acetone (available at Walmart) to some fresh fuel. Attempt to start for several pulls. Let sit for several minutes and repeat until it sounds like it wants to run.

Then watch this video and do it:

I have a husqvarna 261 chainsaw. it will start half the time….the other half…no chance.i changed the spark plug.and im getting very good spark. took the carb apart and cleaned it. checked the plug when it wont start and if its wet…so i dry it. still wont start….and then the next day it may start…sometimes wont. my dad has been working on chainsaws and motorcycles and chainsaws for 30+ years and this has him stumped.when it starts, sometimes it will run for a few seconds. then die. and after a few tries it roars to life. idols good. revs high. and runs perfect. then the next day. ill try and start it, and it just wont. any ideas?
ANSWER : Hi, from what you have written I believe you have a faulty cdi unit. Carbys don’t generally run perfectly intermittently. To test the cdi theory, close the sparkplug gap to approximately half normal gap. If the saw runs fine you have a faulty cdi, shorting ht lead or stop wire. Regards Phil.
