Hi, we have a 873 that is smoking and stinks like you would pour used oil in a pan and light it off. We were told the turbo was bad so we sent it out for a new turbo. It came back still stinking but the engine did have more power. We called Bobcat and was told it most likely was a clogged fuel filter or fuel pump. I changed both filters (one inline on the tank side of pump and the other cartridge on the output side). I also checked the pickup tube and it is clear. We have a bulb inline to pump the fuel into the system and it seems to be working OK as it does pump up and gets hard. After bleeding the fuel filter assembly and getting it running it still smokes and smells. I pumped the bulb while engine is running and there is no change. Where should I be looking next? We do have to keep an eye on engine oil as it does use some. It has 930 hours on a reman engine. The whole unit has 4k hours on it. Any help appreciated.
