I have an Echo 280s that I purchased brand new in May of 2011. I started having problems with it about a month ago. It started with the typical bogging down. I bought a carb rebuild kit, changed the fuel lines and filters, spark plug was also replaced. After all that, I had the same result. I then took the muffler off and checked for build up. There was a little carbon so I cleared that out and still the same problem persisted. I left it alone for a week and now it won't start at all. I know it is a big NO NO to use Ether on small engines but I tried anyways, still nothing.
It has spark, right fuel mixture, new fuel lines and filters, carb has been cleaned. Where do I go from here?
Also, I tried taking the muffler off and starting it and fuel was shutting out of the exhaust for a few pulls.
Any advice would be greatly appreciated because I have no idea where to go from here. I'm dumbfounded
