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 :
Adjust the idle screw, which is the one marked “I,” by turning it clockwise until the chain starts moving, then turning it counterclockwise by 1/4 turn. Make sure the blade stops moving. If it continues to spin, turn the screw counterclockwise until movement stops.
Turn the idle screw — I — clockwise until the chain starts to spin, then turn it counterclockwise slightly. Adjust the screw to find the highest setting possible without making the chain spin. Check the setting by holding a digital tachometer over the spark plug. It should read between 2,700 and 2,900 rpm.

Adjusting the Idle Speed and Mixture
On some float-type carburettors, you can adjust the air-fuel mixture and engine speed at idle. Check for an idle speed screw designed to keep the throttle plate from closing completely, and an idle mixture screw that limits the flow of fuel at idle.
Set your saw on the ground, placing one hand on the handlebar and your right foot into the boot grip for stability, and pull the cord slowly until you feel resistance. Then pull firmly and rapidly until the engine fires and you hear a pop or a sound like a cough. This is the sound of the engine trying to start.
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.
You can do so by adjusting the idle mixture screws to 1.5-2 turns out, and the idle speed screw to 1-1.5 turns in. Warm the Engine Up. The engine`s running temperature directly correlates with proper air and fuel mixtures. So, be sure to let the engine run and reach normal operating temperatures before proceeding.

Echo 14 in chain hard to start – won’t keep running and began to smoke
ANSWER : Hard starting can sometimes be caused by a clogged air filter which is where I would start. Clean the filter, if you have the operators manual it explains how to do this, if you don’t have the manual check Echo’s website to see if you can download one. Next check the manual and see if the carburetor can be adjusted, but be very careful to follow the instructions in the manual exactly or you could do irreparable damage to the needle jets in the carburetor.
