I have a Balay C1306 Butano gas cooker in my house in Spain.
There are 5 hobs and a grill and oven. The hobs and the grill are working fine but there is a yellow smoking fame comimg from the gas plate in the oven. I assume from my school days with a Bunsen burner that the air/gas mixture is not correct. Does anyone know how to adjust this?

Thanks David
