generator - black soot out exhaust (diesel)

[my996duc1]

my diesel generator is putting out a black soot onto whereever the exhaust pipe is pointed.

when camping it leaves a black circle on the ground. if parked at home on the street to colors the curb black.

it would appear to be a soot and I am not sure what I need to do to fix it.

any ideas ?

Assuming no intake issues, how many hours of use in the above picture? What size generator and what all are your powering?

X2 on the air cleaner. Also check the air intake for birds and bees nests. Something is causing your generator to run rich.

I will check the air filter.

Two other Diesels in the group and neither are leaving black on the ground like mine... but they do have a straight exhaust tip where mine is pointed at the ground.

Pretty much normal..

these generators are not new technology eco friendly engines.
