Mep-003 black smoke problem

[captnkirk]

Hello Everyone
my mep-003a is putting out black smoke on the front exhaust pipe.
Any suggestion on where i would start? compression check, leaky injector?
Thanks

Under load? Checked valve clearance? Did this just start or is this the first time you have had it running?

Does it get better as the engine warms up?

just bought the generator, smokes when there is no load.
smokes when started and still after 10 minutes of running .

Try putting a full load on it and letting it run for about 30-45 minutes then see what happens.

Ditto

Also, is it running smoothly? You never want to idle an MEP003A and it should be shut down at normal operating RPM for 60 Hz, but try reducing the RPMs for a slow idle for a few seconds and see if it is running evenly.

Black smoke on a diesel is often related to not enough air. I assume that you have checked for an obstruction on the intake side.

I agree with Rosco...I would look for air restrictions first then check the injectors.

put a good load on it for a while and it cleared up!!
Thanks guys!!!

I love problems that solve themselves! That is if they stay solved!

I suspect it had been ran with a light load for a long time and had some carbon buildup and wet stacking that needed to be burned off.
