Chainsaw Help

[OHhunter]

I think I must have Jinxed myself, talking up my Husqvarna 350.  I was out cleaning up some wind and ice damage along the edge of some fields where we're going to plant clover.  Towards the end of the day my saw gave up on me, and wouldn't start.  I had changed all the filters and spark plug before heading out that day.  Since I have rebuilt the carb and changed the fuel line. Still no luck. 
 
Any suggestions?
 
I have spark, and the plug is getting fuel what can preventing the saw from starting.

Sorry, I can't help. I have run my share of saws but have never tried to do anything but regular maintenance.

One of the things I have noticed at work is that you can have two saws of the same make and one will almost always run better than another. I cannot say why, but there seems to be a tendency for small engines to inconsistent in the way they are constructed.

Hmm...
1. Decompression switch stuck?
 
2. Muffler plugged or worn out?
 
3. safty bar switch stuck?...but your getting spark...hhhmm
 
Can't be overheated and piston siezed...because you can pull the cord to get a spark...hhhmmm.....thats all I got...Good Luck

Had the muffler off not plugged and in good shape, Decompression isn't stuck I've tried starting both ways with on and off, bar kick back off and in good working order.  Keep them coming.

Fuel mixture bad? If you spray starting fluid in the cylinder does it run on that?

[OHhunter]

Thanks for the input, I finally figured it out. The piston and probably the cylinder are bad.  I haven't taken it apart completely yet, but I can see and feel with a pick through the exhaust port that the piston is badly scoured, I'm getting ready to tear it down and see the full extent of the damage.  I'm hoping the cylinder isn't in the same shape but very likely is.  Looks like I may be looking for a new saw, since the price of a piston and cylinder is about the same as a new saw.  Can't really complain about the saw it's been used and abused for I believe 12 years, and never let me down until last week.

I was going to suggest that you check the compression, but I think you already are past that point. Those engines are pretty much all aluminum, and when the get scored, they are toast.

[OHhunter]

Yeah it's toast, got it all apart and cylinder looks as bad as the piston.

I knew that one would be coming when I started this thread.  I still haven't given up her yet, been searching the net for parts.
