Black exhaust JD 330 Diesel Garden Tractor

Posted by Bug Killer on May 05, 2005 at 07:44:23 from (69.37.86.230):

I have a JD330 diesel garden tractor. Been using it for a few years to cut 4 acres of grass. Keeping thinking its going to give up the ghost but it has not, yet.
When I engage the mower deck (spindles and bearings are good on deck, idler could use some attention) always been greeted with plumes of black exhaust.
The engine in it is a 3 cylinder 18hp yanmar. Anyone have any thoughts on reducing the black smoke.
I swapped out the air filter, bled the fuel system, added sea foam to the fuel for the heck of it.
Leaves me with thinking I may have an injector issue, internal engine issue,injection pump etc or something else. I don't have a compession tester for diesels may buy one if the price is right.
In a 8 cylinder diesel I'd crack the injector to find the rough running cylinder on a 3 cylinder how can you spot one?

Thanks,
