No spark

Ok I will do that tomorrow. Something has to be going on. The fact that it started and ran and then just shut off makes me have a bad feeling. I got it up to about 2300 rpm and it sounded good I was about to shoot the timing and just shut off like a power issue. It didn't sputter and spit and die it just shut off now all it will do is back fire it don't even want to try and hit now.
To me that sounds like a fuel issue if it just shut off with no other sign... Just ran out of gas...
