Verify compression of 120psi or better and use new plug

If you've already tried that, then how long has it been since it was used? Was it stored with fuel in it, or did you run it dry before storage? The ethanol blended fuel we are getting now is JUNK! I've bought more spark plugs this year than the last 10 years combined. :mad:
Also had to replace the priming bulb on a Stihl trimmer, and the fuel line on one of my saws.

I had to rebuild 3 carburetors in the past month due to storage with that **** ethanol fuel. From now on i only buy premium ethanol free fuel for my small engines, plus use blue marine grade fuel additive. I'm sick of this junk ruining my equipment. Our government SUCKS sometimes.

I am in the repair business and have NEVER seen this many bad carburetors in one summer! This corn goo has got to go, while it is good for my business, the downtime for guys trying to make a living with their small equipment is definitely taking it's toll.

You say it wont start on ether??

Try pulling the plug ad dumping about 1/2 of a soda cap full directly in there, if still no fire, it is probabally compression.

Saws wear out. If compression is not 120 or better it is time for a rebuild. And if it is below 100, it wont even fire with gas dumped straight in
