G’day team.
Helping my neighbor here with one of his glorious old 555 naturals.
I think this is just a coincidence, but this occurred right after changing all fuel filters.
Symptom is; Starts and runs fine, then after a couple of minutes running, engine stall regardless of throttle opening. Will restart quite well immediately, possibly a little bit of fuel starve type misfire. Starts perfectly after sitting for 5 minutes.
Have checked all filters and lines for vacuum leaks, none found.
Initially I suspected a faulty relay for the fuel shutoff solenoid, however, it’s performing as needed.
What I noticed was the pictured round part, which is held down by two screws. Fuel is leaking around it, and if it’s leaking fuel, I suspect it can also suck air.
Can anybody tell me;
a. what is this?Ā
b. do you agree it’s the likely cause of the issue described?
c. How do I go about repairing this? The last thing I need is springs and balls flying everywhere.
