I got the saw a year and a half ago and rebuilt the carb and put in everything new from tank to carb. It ran perfectly then. Now when I start it, it only runs for a second and then dies. If I take the air filter off, it does spit some fuel out. I read in other posts that it could be metering of the fuel in the carb. However, that seems weird since it ran when I put it up. Or could it be that sitting for so long gummed up the inside of the carb? Any suggestions of where to start? I really hate the idea of having to re-do the carb when I haven't even gotten much use out of it. Thanks in advance!
