I was out cutting some wood the other day. The saw was running fine. I go to start it back up after taking a break and it would not start. The piston is still in tacked and there is still spark. When I go to pull the cord it feels like compression is not being released. It is very hard to pull the cord. Any ideas?

From what I've read the 290 is plagued with all sorts of issues, including a starting problem.  Since there's no compression relief valve, is it easier to pull with the plug out?

Bad clutch?  Is the chain turning when you pull the cord?

Flooded?  Take out the spark plug.  Does it smell like gas?  Is there gas in the cylinder?

I found with my Stihl blower that it has a spark arrester on the muffler, they tend to get gummed up from the mixed fuel is what I was told by a Stihl dealer.  The problem I was having is I would use the blower at a few houses and as the day went on it would get harder and harder to start, I removed the spark arrester from the muffler and no more problems.  YMMV

My 290 runs like a fine watch.  Did you use ethanol gas in it?

it's running rich.  turn the HS (high speed) screw down just a bit.

how old is this 290?
what 2 stroke oil are you using?
what ratio do you mix it at?
have you played with the carb settings previously?
before the saw stopped, was it cutting with good power?

you have to do some detective work on your workbench.  

first, ensure that the chain brake is not binding due to debris or other.  so take the two big nuts off the drive sprocket cover, loosen the chain tensioner and then remove the bar and chain from the powerhead.  now attempt to spin the drive sprocket.  it should spin freely.  result?  

second, make sure that the problem is not just with the recoil starter itself -- in other words, is there a stick or some such in the mechanism?  or perhaps the cord has wound itself in an irregular way and is now binding.

third, take the muffler off.  grab a flashlight.  pull the starter cord and rotate the crank a bit until the side of the piston is seen through the exhaust port in the cylinder head.  is it nice, smooth, and with uniform color?  or does it look scored with vertical black/silver lines?  now again rotate the crank a bit until the piston drops below the exhaust port.  see if you can get a view across at the far side cylinder wall.  again, smooth and uniformly shiny, or scored?

I recently had one of my saws that had the "fuel pick up line" seperate and FALL INTO THE TANK.
