Smoke unit

You have to tell us what the number of the engine is.

It's number 675.

I just rebuild em, you can get a kit from hennings for like $9 includes new wadding, and element

I'm with Matt, there's very rarely ever a need to replace a smoke unit.  New wick and a new resistor, and they're normally good as new.

Thanks Guys! I did not know kits were available. I will contact Hennings. I can see that the fine wire coil around the wadding is broken in a few places. I'm sure my brother shoved a screwdriver in there when we were kids. Thanks again!

That would certainly do the trick, screwdrivers down the stack are a bad thing!

I don't think that had a resistor, but one would work.

 Searching out a ceramic wrapped element, -vs- a resistor, is my choice because I let them go dry too often. The PW units can handle going dry.

 I save the old ones to the bad parts bin for a rewrap if/when I come across some ni-chrome wire. 

Rebuild kits exist for the pill units as well.
