Mower turns over, but will not start
Murray Mower 46800x14A
This problem started last year before the winter.
The old battery was not secured well and slid around and touched the body of the mower and sparked up. I'm not sure if that might have caused something in the electrical system to short? Or this could just be a coincidence.
I replaced the battery and has a good charge.
If I pour some gas, or spray ether into the intake the mower fires up and runs clean / strong but only for about 3 seconds. Then it dies.
Plugs look fine. Not wet. No carbed or gunked up
Gas is passing through the fuel filter and the fuel line is wet where it attaches to the carb.
I disconnected seat safety switch and wedged in small wood shim so connections aren't touching.
What do you guys think this could be?
