Hello, just wondering if anyone could post any links or anything about old oil heaters. Not the pressure fed ignited furnace type, but the gravity fed ones with a simple carburetor. I have one in the garage that originally came from an old railway caboose. The previous owner (5 years ago) used to heat the garage with it but I haven't the foggiest how to clean, light, or maintain the thing. I'm sure if I take it apart I will be able to figure it out, but was just wanting to get and idea of what to do to it to maintain it. Thanks in advance!
