Beautiful restoration VP, I'm looking forward to the video of it running.

Hi busters, it sounds to me like your injector nozzle is stuck open. Excess fuel would explain the black smoke and high compression.
Remove the HP line, bleed off line, valve cover and injector.
Reconnect the HP line to the pump and injector but with the injector outside of the engine where you can see the nozzle.
Turn the engine switch On and with the line lightened at the pump and loose at the injector, bleed the HP line until you are sure that fuel is reaching the injector by rotating the engine.
Tighten line at injector when you see fuel dripping as you turn.
Keeping yourself and everyone around you away and observing all safety protocols when dealing with high pressure injectors crank the engine while observing the fuel spray at the nozzle.
No fuel: nozzle stuck closed.
Obvious Streaming: nozzle stuck open.
Appears normal: Verify by turning engine slowly by hand. Spray should appear as an instantaneous mist with no dripping or streaming.
Let us know your findings.

Powdermonkey - +1 on the good outcome, and going out on a limb to prove and explain your theory clearly. Advancing the cam lobe does make sense as opposed to just changing the start of injection

Your data plate is on the intake manifold, to the left of the coolant overflow reservoir; within the long line of letters and numbers you should see LPW4.

Hi Stu, looks like an LPW4; search for that on Google and you should be able to find info on it.
I've never worked on one of these so I have no tips, sorry.
Someone will come along who can help though.

The S195 is a project by one of our members on this site, and my hat is off to him for a job well done.

Hi, I have read that the Chinese single flywheel engines (Changfa S195 etc) are copies of the old Yanmars (TS130 etc.), and my guess is that that is what these engines are.
Whether they are made in China, Pakistan or elsewhere, I can't say, but they don't look like Petters to me.

Being something of an engine geek myself I find this article very interesting... thank you for sharing.
I may be missing something but I believe the engine from the test paper is a Petteroid, and if I understand mechanical injection, more RPM requires more injection timing advance.
So the 20 degree figure may be right for a Listeroid turning around 650 RPM, but it would likely be retarded for a different engine turning 1500 RPM.
I would expect that a Listeroid turning 650RPM would have quite a knock with injection timing set at 27 degrees BTDC, but I've never tried it so I don't know.
Most of what I've learned is thanks to members of this very website, that being said I've never heard of a Listeroid turning more than 1000 RPM.
I am very interested to know whether your engine is a Listeroid, Petteroid or something else, and what RPM you are turning yours which may reveal to us whether 27 degrees is indeed a magic number.

Have you tried the extra fuel device?
If you haven't, pull the throttle lever back towards the cylinder (fuel off position), lift up and hold the round knob located on top of the crankcase and next to the throttle lever, next push the throttle lever away from the cylinder until it stops. Next, release the knob you were holding and it should stay up.
This is the extra fuel cold start position. Crank engine as usual and if it starts, the governor will kick the throttle back towards the cylinder and either reduce the engine RPM or shut the engine off completely, depending on the throttle.
On most of my E79's the throttle will stay where you set it, but on one of them the throttle is spring loaded and the engine will run slow if I hold the throttle, but the moment I let it go the spring reduces it to no fuel and the engine shuts off.
Just my .02c

Good work, veggie. I have mine run through an old Freon tank with a small amount of steel wool in it. It never occurred to me to add a 2nd tank.
I run across the Freon tanks pretty often, and they're free so I think I will give it a try.

Welcome aboard Brad, similarly I imported 6 'roids about 4 years ago and so far 1 is completed and hooked up to an ST generator and the other 5 are still in the crates.
Post a video when you get it running. It's good inspiration for the rest of us addicts

This is where I got a spare head gasket for my ZS1130. I successfully compared the pictures and measurements to my spare head gasket which was damaged in transit.
