Dear Laurie,
from your pictures I can see that you try to run an Ottaway burner without pilot. I cannot imagine this will work properly because you need a lot of heat for warming up the vaporizer. In a burner without pilot the steam automatic has to regulate from maximum power to minimum standby. I don`t think that the vaporizer and also the injector system works with little flame at standby mode. The drawings of Ottaway burner from SACA storeroom also include space for a pilot. I produced my pilot similar to [
www.steamautomobile.com] and it works very nice. There you will be guided to drawings.
Maybe some other stamers have more experience in a Ottaway burner without pilot
Happy steaming with a new pilot in your burner
