For emergancy use I would put the 40 watt back in till you figure out what yo uneed to do . 94 is better then 107 and the eggs can survive cooler better then hotter for a short time
Do you have a thermastat hooked up to youre heat source?
You might want to try a 40 watt bulb.
If you do have a thermastat you might try moveing it closer to the heat source.
I have mine about 3 inches from mine , I also have it so the thermastat isnt completly aginst the back of the bator so...
