All - I have a Williamson Oil Burner... Model: 1164-18-1 Style: 153 Ser: 7338294
The owner had replaced the nozzle some time ago and has been experiencing issues since. The spec plate shows 1.35 GPH fuel flow, 185K BTU @ 145600 BTU/hr Bonnet.
Does anyone know the correct nozzle size? Most of my contacts have suggested an 80 hollow.
Thanks for the help.
