pilot light too big
The pilot light on my Bowen heater is too big. Instead of a small blue flame, it's a bigger yellow one. Originally I was getting a very small blue flame and it wouldn't stay lit. Then we cleaned out the tube and got a spiderweb out and now it stays lit, but it's too big. The screw that turns the light down is worn out, so I can't reduce it. Is there a relatively easy fix for this?
