So I got a hand-me-down Homelite 16" Bar chainsaw that doesn't run. My brother-in-law says that it has compression and spark and he thinks its a fuel problem. I"m thinking of cleaning the carb, making sure the Hi and Lo screws are adjusted correctly, the air filtere is clean and the choke works as it should. Other then that any recommendations on what I should do to get this thing running? Can I use starter fluid to help get it started?

If it's just not running because of how long it sat you should be able to clean the jet and fire it up. I wouldn't mess with the screws unless someone else has already been monkeying with them. You can start it on starter fluid, but keep in mind that it's probably a 2-stroke, so unless you use 2-stroke starter fluid you're running it without oil to the top end whenever you run it off the starter fluid. If it doesn't pull gas on it's own you should shut it down pretty quick.[Edited on January 5, 2011 at 1:00 PM. Reason : s]

yeah my bro-in-law said it sat for a while with old gas. he emptied the old gas, put new gas in and it wouldn't start. he didn't do anything after that. i'll try cleaning out the jet, put new fuel and give it a shot. thanks!

Probably got a Walbro carb on it, just maybe a Zama. Both are internal pump metering type carbs, and they really don't tolerate dirt and goop very well. I'd take the carb apart and clean everything really well with a decent spray carb cleaner. Make sure your needle and seat at the fuel inlet are clean and unobstructed, and all orifices going to and coming from the pump diaphragm and one-way valve wafer are clean too. Don't stick anything in them; just spray well to clean.

dude. check the recon section at the home depot in garner. they had 10-12 saws there last time I was out that way from $85-$110

I've never taken a small 2-cycle engine carb apart but i'm willing to give it a shot. i plan on taking it apart saturday, cleaning it really well and seeing if i can get it running. i'll document everything just in case i need some help.^ thanks for the heads up. if i can't get this one running i may go that route. do you remember what brands they had. i would really like to get a Stihl or Husqvarna.

Probably the carb, gas sitting over a long time tends to clog up the small passageways in there and I've seen a few small engines end up this way after a winter. Anything you don't plan on running for over a few weeks to months (lawnmowers, chainsaws, weedeaters, etc) you need to drain the gas and run it till it conks out.

so I got the saw running. its was pretty easy. just emptied old gas, took it apart, sprayed it with carb cleaner, cleaned it up real good, put it back together, put new gas in and it started on the 5th pull. been running strong since. not bad for a saw i got for free. one thing that is annoying though. i can't get it to cut straight. it keeps veering to the right as i cut larger diameter pieces. i would sharpen the right side saw teeth and this would help but after say 10 or 15 long cuts it would start veering hard, getting worse with each cut. WTF is going on?

My guess is that your bar isn't true. Fairly common on the cheaper laminated bars, especially after they heat up. Here's a quick test...flip the bar over and run it, see what happens.You might want to see how the chain tracks in the bar, and if any lateral pressure causes the teeth to cock to one side any. The actual edge of the bar will sometimes channel a bit from chain wear, and the edges are beveled inward. They should be flat.
