Black smoke after cleaning injectors

[Hhinai4]

Hi team,
I have kubota tractor L3250 with engine v1902. I took fuel injectors to the shop and they said some of them like clogged, they cleaned them, once i start up the engine after while a black smoke is coming out! Any advice?

It sounds like the engine is now running rich. If the smoke is continuous, I'd take a hard look at the newly cleaned injectors, and also verify they were re-installed correctly.

is it a reputable injector shop, did they warranty the work, & what is their take on the smoke?

Before dashing to the shop with the injectors make sure your air filter and air path are clear.

Why did u take them out.??
U must’ve had a problem..
If it was black smoking when you took them out and it’s black smoking when you putm in.. move on, the injectors aren’t the problem..?? THATS IF, the injectors were done by someone who knows what they’re doing..
