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 :

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.

The reason for that may be you`re using the saw at altitude or the carburetor adjustment has simply slipped. The saw also won`t operate well at speed if the air filter or spark arrestor or carburetor are dirty.
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.
Check the Airflow

If this breathing system gets compromised, you will start noticing sharp power losses. Clean the air intake areas around the air filter, carburetor and air filter; replace bad or worn out filters. Also, clean around the cooling system near the starter side and around the fins on the cylinder.

What is Bogging? When a dirt bike bogs, it simply means it`s not getting enough fuel and the engine sputters or stalls at full throttle. There are two common types of bogging: lean bog and rich bog, distinguishable by how the bike sounds when you throttle.
The “Bog” simply means the engine is not receiving enough fuel when you go to wide open throttle. While there are other issues that may cause similar reactions within the carburetor, often the problem can be traced back to the accelerator pump system. Incorrect adjustment is the typical culprit.
An engine stalls when it`s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it`s idling, adjusting the idle screw, which usually is marked LA, should help.
Carburetor Idle Adjustment

The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn`t really slow.

There are a few reasons why your car might be bogging down when accelerating. One reason could be that your engine is low on oil, which is causing it to seize up and not work properly. Another possibility is that your spark plugs are dirty or worn out, which is preventing the engine from igniting the fuel properly.
There are several reasons the Chevy 350 bogs on acceleration, including problems with the ignition system, fuel pump, air filter, catalytic converter, or muffler. The most common cause is that your Chevy 350`s fuel filter is clogged or the pump isn`t working properly.

Chain saw won’t start – pull starter pulley hard to pull?
ANSWER : If it worked fine the last time you used it, then pull the spark plug and try pulling the rope. See if it’s easier or if gas shoots out of the plug hole. I’ve seen this happen when the diaphram in the carb goes bad from sitting over winter. It loads up the cylider with fuel and makes it very difficult to pull the rope. If there is no fuel in the cyliner and it’s still hard to pull, make sure there is nothing binding the clutch/sprocket. I’ve had chucks of wook lodged in there that caused it to bind the crank output, which resulted in a hard pull on the rope as well.

I have a Poulon chainsaw problem. I bought it of a “E-bay” type site. Have replaced the starter cord, put a new fuel line in, replaced the fuel filter and serviced the carb. I’ve adjusted the H and L screws as best i could, but the idling seems to fluctuate. Goes from idling too fast too just dying. Also when i got it to run for a little while and started to use it, the chain would go tight on the bar obviously adding extra drag on the motor, causing it to stop…., can you please help ?
