Hello,
I am in Canada and have an oil fired furnace I use in my back yard to heat my "play shop' where I woodwork ...fix cars...etc.. I have this furnace on a switch so when I am done woodworking or whatever I simply shut it off when I am not using it. The problem is that on a weekend when I decide I have time to go back to the shop to play...I walk into the shop and throw on the furnace (room temp about -10 Degrees Celcius)and the furnace dosen't light right away but still pumps fuel into the combustion chamber....when it does light some 15 or so seconds later, it is trying to burn all the deisel oil from not lighting up right away which freaks me out...IE:.....big roar...black smoke etc... then it settles down and works fine... I think it's something inside that needs cleaning.............. perhaps the contact points that make the spark to ignite the fuel? Would there be a website where I can see a "hands on" cleaning of one of these things?....I did a Google search and came up with nothing....Thanks in Advance...Jim
