Good Tip thanks.

I now that a sign of a bad pump is poor idle. It idles fine then unpredictably just shuts off. Not a hard thump just it can idle for 3 mins solid and then just no warning cuts off. Then it doesn't want to start. Let it cool and set for several minutes and it starts up and runs again like a champ and then out of nowhere just zip its off and won't start back up.

I have only had one pump go bad in my time with the DZ engines and that was many years ago. In fact I believe it was my first proto type 140DZ.

I have a pump here that I swapped out with a guy a couple years ago that we thought was bad at the time. Pump from my Backup engine and his problem were solved. I guess its time to play with it and find out why its bad.
