Help finding stuff for my lamp

[Dave Daughtrey]

I have a 1975 model Lava lamp that no longer works. It lights up but the goo doesn't blob and rise like it should. It is a 1975 model 300 Carlisle. the only thing different is the spring in the bottom is broken.

40 watt high intensity bulb

Oh, well then. That's weird. What kind of bulb is in it? Should be a 40W intermediate.

I have let it run for several hours like 8 or 9

How long have you let the lamp run before you determined it won't run? They can take several hours to get moving. 

And what do you mean the spring is broken? Even if the spring doesn't connect end-to-end it can still work. The important thing is that it's at the bottom and not rusted or full of gunk.
