My echo cs-300 will start & run fine for a few seconds,, then will die. I suspect the gas vent is plugged. I see the hose,, it goes way back into the motor. How do I get to the end? I suppose it has some sort of “duck bill” fitting. Many thanksRichardLovelady Texas.

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 fuel tank may build excessive pressure due to a blocked vent. This could cause fuel to spray on occupants or bystanders when opening the fuel cap, potentially causing injury. Additionally, if an ignition source was present, this could create a risk of fire, causing injury and/or damage to property.
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.
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.
My chain saw starts and then dies what is wrong? This could be a number of things and is most likely fuel or storage related. Over a short period of time, fuel will become stale. If the unit is stored with stale gasoline, the system will become clogged or restricted.
What is the fuel/oil ratio for my product? A 50:1 ratio with 89 through 93 Octane fuel can be used in all ECHO 2-stroke equipment, provided the oil is ISO-L-EGD and JASO M345 FD certified.
Oil mix ratios explained

If your manufacturer recommends a 50:1 fuel/oil mix, it means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as shown in the chart below.

A tank vent may seem like a small component of the system, but it is absolutely necessary. If there is a pump attached to the tank and that pump is drawing suction from said tank, it is imperative to properly vent the tank.

Echo chainsaw how do you remove the clutch from an ehco cs400evl?
ANSWER : OK I looked at Echousa.com and see that there shoule be a hex nut on the side where the clutch is. It doesn’t specify whether it is left or right hand thread. but what I used to do is we have a plastic plug to put in the cylinder to stop piston from moving and then putting a ratchet on the hex nut. without the plug you can try an impact wrench to BUMP the nut in forward and reverse to remove it. Make sure the switch is off before attempting either action. You can look at the manual or parts explosion at the site I listed
