May 1st, 2009 01:30 AM #2mukhang may singaw na yang exhaust manifold gasket nya at baka may butas na rin exhaust pipe mo pa check nyo.
mukhang wala rin sa timing ang andar ng makina kelangan din ng tune-up at mukha rin palitin ang sparkplug nya.
dapat yun nag pa overhaul sya ng makina pinadamay nya na rin ang karburador para malinis at mapalitan ang mga jettings.

Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.
Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.
