Weil-McLain AFG rumble!
I don't know what else to do!
My oil burner was working well, but the fuel shut-off valve was jammed open & it was 60+ yrs old, so I decided to replace it! Wow! Can't even figure how the burner fired when I saw all the "crud" in there! Anyway, long story, short, figured I would change the filter, nozzle & pump screen & what a mess! Changed everything out, set electrodes & put everything back together! I bled & primed & fired up the burner, but now every time the burner fires up, it starts right up & runs great for a few seconds, but then starts rumbling & "booming"! After a short time it smooths out again! What's the problem? I thought maybe air, but thoroughly bled everything! I also blew the oil supply line out & reprimed up through the filter! Any ideas?

Ok, problem solved! Turns out that eventually, the unit would run, but it wouldn't fire and would lock out! It appears it was a problem with the solenoid, either not working properly or clogged somehow!
Thanx!
Thanx!
