Hello. I'm having a tough battle with this mower and I'm hoping you guys can help. I picked up this Craftsman 30" rider recently that wasn't running. At the time of purchase, I could see the coil wire was chewed by a mouse, so I assumed it would be an easy fix. I was wrong. I replaced the coil and did get it to start, but only in choke mode. As soon as I move the lever off choke, it starts over revving like crazy and backfires. It's actually pretty scary. I was told it was probably the carb, so I bought a brand new replacement carb, but same problem. The motor is a 13.5HP OHV Tecumseh. Can anyone help me figure out what I'm not doing right? :smile:
