Hey guys I have a 20 hp farmpro / jinma actually a 2420. I’ve been battling for a while!
I’ve resorted in a complete rebuild inside and out. Everything is brand new! Yes oil pump also.
When I first cranked it up I would get about 20ish lbs of oil pressure at a little above idle. When I reved the engine towards the upper end, I could reach about 40ish.
I’ve put about an hour on the thing to break it in and now all I can get topped out is 20 lbs. At idle it’s about 5-10!
I have no idea what this thing calls for as what the pressure should be at all.
To me this seems low but I don’t know.
I’ve attempted to dicker with the pressure regulator on the oil filter housing and I get no change no matter what I do.
Any advice ideas or is this just normal??
