Cub cadet UTV with Perkins 403c diesel running rough

I have a UTV with caterpillar/ Perkins 403c diesel engine loses power while driving and smokes, exhaust also has a hissing sound. Was wondering if it’s injectors or a more serious problem

From a glance those look ok with out a test. Dont smash the tips wheres the hossing sound coming from a plugged up spark arrestor perhaps

Thanks.I believe your right about the spark arrestor it was plugged up pretty bad
I didn’t even think about that

Welcome to the Forums! Glad to have you.

How do you like the diesel powered UTV?

As soon as the right project comes along that I can "cough-cough" justify a UTV I want to buy one. Hard to justify one for a 1-2 acre site.

Thanks. I absolutely love it we got it new in 2006 it’s not built for speed like some of the newer UTV but is a workhorse i use it everyday on the farm . I sure do miss it since it’s been down
