Hello friends,
I am just about at my wits ends with this one...
Symptom: Engine runs great for 40 minutes, then sputters and dies.
This is reproducible; it stops at the same location every time I go out.
What I have done:
1) Drained and cleaned the fuel tank, re-filled with new gas.
2) Replaced fuels filters, both Racor and polishing.
3) Checked Facet fuel pump. It seems to be pumping gas OK.
4) Adjusted oil pressure. It had been dropping too low so I turned the adjusting screw inwards and now have a minimum 20 psi.
After all that, it still does the exact same symptom. 40 minutes of running great, then a sputtering death. Sounds like fuel starvation, with dying surges until stopping.
What to do next?
1) Disassemble the Facet fuel pump to look for a problem there. Anybody ever done that?
2) Could it be the carburetor? It starts easily and runs great until 40 minutes of run time.
I would really welcome any suggestions at this point.
Thanks!
