i have a uho83lc best running most dependable machine ive ever had,i do not hire it out so it sits alot . so recently i fired it up walked it a while and got water in fuel problem .i been called a lot of things but never a mechanic. i drained the tank vacuumed it out, vacuumed the lines out fired it up every thing was fine thoroughly cleaned the machine soaped and pressure washed the crap out of the machine , i got years of funk out of center compartment , washed engine compartment. the next day i went to fire it up , i have had this machine for 7 or 8 years and always just touch the key , starts an you can barely hear it run, until now ,crank it and bogs down and goes dead, made a heck of a horrible noise and die after a few times idled it up and kept rolling it till it cranked , the noise stopped and the engine is running under a load, you idle it down and it dies . when id crank at normal idle and it would die there would be bad black smoke . i dont see any differential pressure sensors on this one and i cant find anyone that knows anything about these machines , regular diesel mechanics see the numbers on the machine and close their mind to every thing about the machine. help please
