It's a Lombardini diesel. Are they a subsidiary of Kohler? If you don't want to go back to the dealer then find a diesel mechanic who works on commercial equipment. Any diesel guy should be able to tune your mechanical diesel to run right.

Look up posts by member Whitbread. He has some tips on the diesel to get more power. If you don't want to tackle it, then share it with your new mechanic.

The shop did something to the engine that isn't good. It isn't making nearly the power it was before. The engine is very slow in throttle response and coming up in RPMs and sluggish to come down in RPMs. The governed RPM seems way lower than factory.

I found a Kohler authorized service center in Bozeman. Phoned them and they said they know nothing of these engines.

Sounds like the shop retarded the timing instead of advancing it.

Smelly Cat. 08 700 Diesel. Smoke screw tweaked for smoke. RTR Flex bracket with a little lift. Stock looking hollow muffler. Mud Pro snorkel added for looks. Two batteries, because two is greater than one. Other stuff to be added later.

I just saw this post. If you haven't sorted this out, read Whitbread's post, go to page 15 and he has instructions how to advance the timing and turn up the fuel. Looks pretty simple, once you dig into it. I read his whole epic post last night. Don't know if he ever got a kit out for a turbo, but that sounds like the ultimate power option.

Something definitely isn't right. Yes it's going to be slower overall with the tracks, but it shouldn't rev slower. That's definitely something not done right in the tune up. I'm outside of Gaylord MI, if you can get the machine here I'd be more than happy to sort it out for you! My email is, I don't get on here a ton these days.

There is a Canadian guy on youtube (V10PDTDI) that is running tracks on his Diesel, he has a turbo conversion. Looks like he's zipping around pretty easily in the video.
