# Why doe the gas furnace blow black smoke?
Get a life. black smoke means unburnt fuel
YES
buy a cummins
you can use chips, power mods, and smoke switches.
to make a diesel blow black smoke is usually done by turning up the fuel pump.all this accomplishes is to much fuel and the black smoke created is mostly un burnt fuel that is being wasted
You could possibilly blow the head on the engine! It will blow black smoke out of the muffle.
The black smoke that a diesel engine blows out is fuel that is unburned. The black smoke can be caused from over-fueling, poor fuel quality, or dirty or worn fuel injectors.
Black smoke can be caused when there is an improper air to fuel ratio . This can be anything from a plugged air cleaner,injector,turbo....
Black smoke from the exhaust it a symptom of an overly rich fuel/air mixture. Have this repaired or it will destroy your O2 sensor and catalytic converter.
You don't want your gasoline powered engine smoking black. If it does, then you have some SERIOUS mechanical problems. Black smoke is for diesels. Keep it that way!!!!
Poor a pint of oil in the gas tank that will get her smokin! :)
Black smoke is : too much fuel and not enough air, a faulty injector (s). Take out the injectors and have them tested before you do engine damage.
