I’m new to the forum - been a computer user for decades but searching this forum is not producing results - suggested instructions?
I have a 770 with 400 hours on it.
Although not many hours for its age I have changed the fluids several times over the past 10 years.
I borrowed a 48” 3 point field mower and have been mowing for about 15 hours, running at 2,600 RPM. Suddenly the power of the 23 HP engine dropped (RPM down to 2,300) while mowing up a slight incline. The engine seemed to have a ‘mis’ (but no stuttering). Even putting the rig in neutral did not clear it up, however after taking the load off and maintaining full throttle the ‘mis’ clears up in a few minutes.
I pulled the air cleaners off and blew them out - while they were clean with I started the outside one was quite dusty - they both cleaned up good - I can see light through both.
I thought it might also be something in the diesel; although I used PRD in all of my stored diesel and gas. But with that said I poured about 6 ox of seafoam into about 2 gallons of diesel in the full tank. I ran it and then let is sit for a couple of days.
Back to mowing today and the same thing is happening.
Injector? Seems that would be consistent.
Fuel filter? Seems would also be consistent.
Any suggestions would be appreciated.
