Briggs & Stratton (Mower Dies After 10 Minutes)
I had a surging problem (engine reving up and down) with my Craftsman 550 Series 4 Cycle Engine (Engine 10T802-123B-B1) Model Number 917.385127. I changed the diaphragm and everything was working fine. After 10 minutes, all of a sudden the mower stopped running.
I looked on the side of the motor and the primer button had sucked in. I waited a couple of seconds and the primer pucked back out on its on. I just pulled the string (without priming it) and the mower started right up after the first pull. After a couple of more minutes, the mower stopped running again.
I checked on the side of the mower again to see if the primer was sucked it but it didn't do it this time. I pulled the string to start it but it wouldn't start. I pushed the primer button to feed it some gas. I pull the string and it started right up. Can anyone tell me what the problem is? Thank you.
