The engine is burning rich. Clean or replace the spark plug and air filter. If you still get black smoke, close (rotate clockwise) the carburetor needle valve 1/8 turn for a leaner mixture.
It is not meant to smoke. It is running properly if there is no black smoke.It is not meant to smoke. It is running properly if there is no black smoke.
300zx twin turbo lots of black smoke and running rough
It is difficult to start and emits a smelly white smoke once running.
isuzu trooper e.f.i 1991 black smoke and running but no power
If its black smoke you are burning oil possibly due to oil getting in your exhaust by tilting the lawnmower on its side or your rings are allowing oil by.
Black smoke is always too much gas. Its running too rich. Poor mpg! A good mechanic can scan it in a minute. Might be an O2 sensor failure causing 'open loop' all the time.
Sensors do not make an engine smoke, unless one is causing the engine to run rich.=Black smoke = Overly rich fuel/air mixture.==Blue smoke = Burning oil.==White smoke = Coolant entering the combustion chamber.==The O2 Sensor would be suspect if it is running rich.=
No. Black smoke is created when your truck is running Rich meaning that you are getting to much fuel the black smoke is just simply unburned fuel
It could, if it's leaking.
When you overfill oil in a lawnmower it will smoke when you tip it sideways while mowing,it has no harm
The three things that could cause black smoke which come to mind are: 1) You have a belt or pulley problem which is causing the belt to slip and burn. 2) You have an oil leak that is getting on to the exhaust and burning. 3) The mower is running rich. Which means it is getting too much gas. The most common of these is choice 1. Oil leaks don't normally get onto the exhaust since most exhausts aren't under the engine. The running rich problem also does not normally come from under the mower. It would typically come from the exhaust unless it has an exhaust leak.
Blue smoke is oil burning, White is steam(water), Black smoke is unburnt fuel.
