Echo CS8000 keeps burning up spark plugs

I have an Echo CS8000 that will run for 45 minutes to an hour then it burns the spark plug up (it does not foul it actually burns up)
This happened two times and now the saw will not even attempt to fire.The saw just had a new intake boot installed on it and the carb. rebuilt on it about three weeks ago.
I just purchased the saw from an individual and when I went to check it out the saw fired up and ran great so I bought it but after 45 minutes run time under load the problems started showing up.
Has anyone else had this problem or does anyone have any ideas on how to fix it ?

I'm not a small engine mechanic but it kinda sounds like its running to lean, not sure if there the same but if 4 cycle engines run way to lean they detonate and can melt a piston. Most of the time they will run fine under no load but once under load it will cause the detonation. If you have a compreesion gauge see if it has any compression if you dont have a gauge just put a finger over the spark plug hole and pull the starter to see if it builds any compression, if no compression probably a hole in the piston or bore hope this helps

I have a CS-4400 Echo chainsaw that wont start. I don't think it is firing


1st thing let's check the spark.remove the plug leave it connected to the wire and ground the side of the plug to the engine. and have someone pull the started rope. watch the gap area of the plug for spark. make sure the plug is gap to factory specs, and hold it by the rubber booth. and the on switch is in the run position. good luck Tom

Echo chain saw has no spark how to fix


Not being facetious here... change the spark plug as a first step. They require regular replacement. If that doesn't work, use a multimeter to check that the spark plug wire is actually releasing electrical pulses. If it isn't, you'll need to keep moving further up the line to the coil.

Echo edger stalls when gas is pressed. It is easy to start but will only idle and has no power to work.


Check and see if the muffler and/or exhaust port is plugged with carbon. Many 2 cycle mufflers use a small metal screen called a spark arrester that can get plugged by carbon and will not allow the engine to rev up. A small hand held torch works best for burning the carbon off of the screen and from the insides of the muffler. Hold the screen with a pair of pliers while heating it up. Same thing with the muffler. Carefully tap the muffler after you have burned off any excess carbon to remove any large pieces still inside. You can carefully use a small flat blade screwdriver to scrape out any carbon from the exhaust post (opening) in the engines cylinder.

Echo CS600P saw, brand new, ran it last weekend for about 30 minutes. Started and ran flawlessly. Trying to start today and it seems as if it is flooded. I've taken off the spark plug, turned it upside...


Try a new spark plug and make sure gap is .030.and check the air clener and make sure it is not plugged up.you can clean it with soap and water then dry it out.if this doe,s not work you have a carb problem.

My saw is only 5 months old and will not start worked fine when i first got it stored it for a few months with no gas in it now it wont start


Remove the spark plug and clean the electrode at the end where the spark jumps across the gap.
Pour about 5ml (or one teaspoonful) of fuel into the opening, where the spark plug came out of.
Dip the electrode end of the spark plug in the fuel so the spark gap is wet
Replace the plug and try to start it.

The fuel you poured in the opening will burn and should get the saw going. You may need to repeat it 2 to 3 times. Don't use anymore than 5 ml of fuel or you'll just flood the saw.

When you were leaving the saw in storage did you just empty the fuel tank or did you let it run until it ran out of fuel. If you emptied the tank but did not let it run dry there would still have been fuel left in the carburettor. This is what causes the damage. If there was fuel left in the carburettor it will have formed a gel in the carburettor jets. If this happens the only way to clear them is to bring it to a mechanic who'll need to strip it down and clean the jets.

I hope this helps you.

Oil collecting in exhast, and running out on floor, saw won't fire, has been running good ,i have an echo md.#302...help


Try putting a new spark plug in it.Check your gas and oil mix.you might have too much oil in gas this will cause the oil to leak out the exhaust because it will not burn off the excess.
