Mower still acting up a bit. Think buying the knockoff pump may have been a bad idea. I'm on the right track with fuel delivery being the issue though as it instantly ran better and didn't shut off like previous. I've had a positive cable issue forever. Even put a new cable on it but it corrodes like crazy. And sometimes have to fumble with it to get it to crank. Yesterday it did that, then acted like it didn't want to start and wasn't getting fuel. Once I got it running it ran fine the entire time I mowed. Then restarted when I went to help the neighbor mow his, ran fine then too. I'll keep an eye on the new pump/filter and see if the filter is full next time it dies. With the old pump it would always restart. It died on me last weekend and wouldn't restart. Filter was not full. Pulled the hose off the top of the pump and cranked. Spat what seemed to be an inadequate amount of fuel out but I am not sure if it will pump correctly in the open air like that, as I am sure the vacuum of the pistons assist these lil pumps.
I shut it off while mowing the other day to do something for my mom. When I came back out it wouldn't start. Thought it was the starter. Pulled the started off and followed a bench test video on he tube. Tested mine several different times. It wouldn't spin, nor eject. So I ordered a new one. Still nothing. I have got a wiring issue or something somewhere. When I turn the key on I can hear the fuel pump kick on but the starter doesn't even try turn. Battery tests at over 12v, tried jumping it off my Kioti just to see, still nothing. To the wiring diagram I go. I had to replace the pto switch a few years ago. I wonder if thats bad again and the brain thinks the blades are engaged...

Sometimes this is how repairs go… start at the most obvious, and then keep spending money!

Fuel pump and filter probably were still needed. I could be wrong....depending on how its wired....but I wouldnt think a faulty PTO switch would cause the random dying you had while mowing. Its a safety that will prevent it from starting....but once going and with your but in the seat....whether the "brain" thinks the blades are engaged or not shouldnt have any effect and make it want to kill the mower
