My 25/2 running about 720 rpms runs out of steam at 5k load.
I believe the governor spring is too heavy.
The linkages are free and easy to swing from stop to full throttle. No binding.
I added a spring or two to take all the slop out. Time was not a factor so time
was extended for proper set up.
Injector timimg, pretty much the same deal. I spent hours setting and adjusting
timing on valves and injectors.
Starts well, runs good.
With that said I am convinced the govenor spring must be on the heavy side.
Near a 5k load the engine is working harder and the hz will drop from 60/61 to 57/58
on the gen head. 11kw "stamford"clone, so I don't think thats the problem.
The rpms are dropping about 45. 720 to about 675 give or take.
The exhaust temps are within 4 degrees of each other under load.
Cooling temp leaving the heads near 190/200 with return at 160 or so.
I would think the beast should easily pull 8 or 10kw before it starts to
load up.
I say softer spring.
What y'all think ?
