I've got a Poulan Woodshark S1970. It's an older saw but not many hours on it. I used it with no issues several weeks ago. The following week it would no longer start. It won't even attempt to start, like the spark plus is unplugged.
Here's what I've done so far.
1. pulled the plug to check for spark. The original plug was a little dirty so I put in a new one. New plug shows a nice blue spark. Nothing. I tried a second new plug. Got spark but no ignition.
2. Checked fuel. New plug smelled of fuel when I pulled it back out so I assumed it was fine. Just in case it was flooding. I let it sit for a day with the plug out. I primed it with a little gas in the plug hole and tired again. Nothing.
3. Installed another brand new carburetor. Changed all of the fuel lines and filter. Nothing.
4. Checked compression. 150psi
5. Made sure airgap at coil was 0.35
So what's next? Is it possible a still have a bad coil that's not firing under compression? I suppose I could check resistance on the primary and secondary but I don't know what the specs for this coil are. Anyone of any other ideas?
Thanks - John
