Chainsaw (Shindaiwa 377) won't start...tried the previous threads...

It just had some work (tune up) done a few weeks ago, and I ran it yesterday for about an hour. I left a bit of fuel in it overnight(i now know this is not OK). Couldn't even get it to burp today. Figured I had flooded it, so I let it sit for a couple hours (watched a game). The spark plug sparks. If I try and start it for awhile, the spark plug will get moist.

What do i try next (preferably short of taking it back to a shop)?

There's no reason not to leave fuel in it overnight. It's fine.

If you just got it worked on, I would be tempted to take it back. If not, you can check for spark, check the plug to see if it's wet, and see if you can determine what is going on with it.

i checked for spark per your response in another thread and did see a visible spark. and it does get moist after pulling for a minute... sounds the same as it did yesterday (does that indicate good compression?). the thing that worries me about the fuel is that it was a bit (maybe 45 days, but also spent some time in the sun) old. ...apparently this can 'gum up' the carb? could this be whats making it so i get 0 burping/fire?

If it ran fine the day before on that fuel, then it should run fine the next day. For some reason I missed that you checked for spark and wet plug. Take the plug out, dribble a small amount of gas into the plug hole, put it back in and hold the throttle wide open with the choke off and see if it will start.

THANK YOU!!! That worked. I had tried a dab of fuel in the carb(I have vague memories of that working on an old Chevy as a kid), but not the spark plug hole... It started, and I've run it for 20 mins already.....what was the deal???

It wasn't getting enough fuel either because the choke isn't closing properly, the carburetor isn't priming properly, or ???
