Just bought a 312-8 from someone who needed the money who said it was his dad's and ran good last fall but couldn't get it to start this spring. Got it home and it turned over fine but no fire at the plug. I didn't realize this old of a machine (1990 I think) came with all the safety switches. There is no seat safety switch so I assume it was bypassed, but I have to push in the clutch to get the motor to turn over so that one must still be active. I found the pto switch and it seemed to move ok and click, and the two fuses checked out ok. Just need to know where to go from here. Thanks.:confused2:
