My panda had 25 hours on it and it conked out. I called fischer and described problem (engine would not start but could hear fuel pump running). They said it was probably a relay, and explained how to test it. Sure enough one of the relays was shot. They recommended that I change fuel and oil filter, clean strainer and change impeller. They said generator was 3 years old, but even with limited hours, it made sense to do that. I then asked about valve adjustment and they said not enough hours and I needed at least 50 hours otherwise I was wasting my money.
Called a local service guy and he did all the work described above for under $250.00. He said the fischer panda was a star and would last a very very long time.
Anybody got a preferred diesel additive?
