th new spark plug.
Experienced gardeners share their insights in answering this question :
This could well be an ignition problem, now that it does not go remove the spark plug, rest it on the cylinder ( away from the plug hole ) and check for a spark, if there is no spark it will more than likley require a replacment unit, if there is a good spark it must be a fuel issue, replace the fuel filter in the tank, check the fuel hose up to the tank for splits or cracks, check the impulse tube from the carb pump cover to the crankcase for splits.

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.
The engine is likely to stall when the filter gets plugged with dirt and dust as too much air is filtered which deprives the engine of adequate air which is necessary for combustion. The air filter on a chainsaw is located at the rear. Loosen the fasteners and remove the filter to inspect for any dirt.
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.
If your electric or gas saw`s chain won`t turn around the bar, chances are that the chain brake is stuck. On some saws, resetting the chain brake is as simple as pushing in on the side cover of the saw`s body with one hand, and pushing the chain brake forward while grabbing the top handle with the other.
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.
What Causes Chain Saw Kickback? There are two circumstances that can cause kickback when using a chain saw. The first occurs when the moving chain at the tip or the nose of the guide bar strikes an object. The second situation is when the wood closes in, pinching the saw chain in the middle of the cut.
A Husqvarna riding mower commonly dies when blades are engaged because the grass box is not fully closed. Other possible causes include: Grass Box Misaligned. Grass Box Sensor Wiring Loose.
Three possibilities: Your chainsaw is too small/underpowered for the job. The chain is dull and needs sharpening. You are applying too much pressure during the cut.

Chainsaw stalls Chainsaw is 4 years old and has a history of moderate use. After I ran the saw about 1 minute on plain gas (grabbed the wrong gas can – ouch) the chainsaw sputtered and stopped.
It didn't seize, and the pull starter never became more or less difficult than normal. The engine would continue to start if I pressed the prime bulb and engaging the choke, but stall again after 10-20 seconds. The temperature that day was about 50 degrees F and I was running the saw with the “cold plug” installed (per warm weather running).
When it refused to keep running I did the following:
Flushed the fuel tank (that's when I saw the gas had no oil in it).
Ran hardware wire through all of the fuel lines.
Replaced the fuel filter and spark plug.
Cleaned the air filter with a nylon brush and compressed air.
Same behavior (start then stall in less than 20 seconds). I made at least 20+ attempts to start it.
I removed the carburetor and, though it looked perfectly clean, I took off the top and bottom covers then sprayed everything with automotive carb cleaner and blew out the passages with compressed air. The gasket and diaphragm looked new. No pinholes in the diaphragm when held against a bright light. I reinstalled the carb but got the same behavior (start then stall in less than 20 seconds). I again made at least 20+ attempts to start it.
I disassembled the short block and saw that the piston has some slight scoring on it. The ring is clean and I verified that the piston ring has .001 clearance between it and the piston ring groove all the way around with the ring held tightly in place (I was thinking that the piston might have become deformed if it did indeed get too hot when run without any oil premix).
The cylinder wall has no scoring and there isn't any signs of melted aluminum anywhere. The crank is clean as was the inside of the crank cover.
I reinstalled the crank cover using permatex non-hardening gasket goop and torqued the cover bolts to 10 inch pounds. I reassembled everything else per the exploded diagrams in Echo's “parts manual” for the CS400.
During assembly I took note that both the carb gasket and intake boot look like new.
Still the same result: press prime bulb once, engage choke, pull a few times and it starts but stalls after 10-20 seconds.
Not sure what to say other than its fuel starvation, if not already done replace the fuel filter in the tank, if no better i would suspect a massive air leak, so replace the crank seals, if there is no primary compression in the crankcsae fuel will not pull through the engine, good luck.
Engin runs fine at idle but stalls out at high idle and wont rev up.
Hi 5flash… Get an assistant and a can of starter fluid. Remove the air cleaner and spray some starter fluid into the air intake. Start it up and spray the starter fluid as you move it to high idle, repeat until it works properly. Joe
Thanks for choosing Fixya!
I need the spark plug gap for an Ariens ST624E. the spark plug = 21533500
The recommended setting is .030″
Mantis tiller stalls out, Haven't used it for about 9 months, but had stabilized gas in it. It would run but had no power, so I replaced the gas with new fuel – Now it will only start for a second and wont run at all… Help!
If you haven’t already, check the spark plug. Might be carboned up.
What should the spark plug gap be on a weedeater trimmer 25cc
No spark at spark plug and unit will not start
What kind of gear is it. is there an on off switch? could the wire from the switch be earthed because its worn thru?? check this and see. lets face it. no spark it wont run. try another plug too. sometimes thats the answer
What is the spark plug gap for a NGK BPM8Y – Echo Cs-400 Chainsaws
20-25 thou which is around 0.6mm
Does not run, will start with starting fluid – Mantis 2-Cycle Tiller
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:
