branson 35 hp injector problems makes crazy bad noise then smooth

[scubacarib]

it bangs and clangs then smooth helping my friend get it started bought in the field put on a new starter and lift pump new battery and filled with hydraulic oil runs good then starts raising hell then smooth again could it be the injector pump or injectors
also three point dose not move acts like its stuck

Could there be air in the injector lines?

Yes, air reaching the injectors will hammer something fierce.!!
It’s usually from cracked rubber lines and/or a failing supply pump and dirty/clogged filters..

May try fuel additive to lubricate the injectors

Got it bled and running but not well so I did a compression test and it looks like the motor is no good the compression was reading about 3:40 or 60 on one cylinder 220 on another cylinder and 140 or so on another cylinder I'm thinking the engine is the same as a Cummins 1700 3 cylinder 35 horsepower but on the sticker it says kukje instead of Commons looks like it would be pretty easy to rebuild Branson wants to sell each part separate it would be thousands I see rebuild kits for the Cummins starting at 480 and going to 7 or 800 so I guess my main question is does the 3510 2015 year have a Cummins engine
