Hi Casey

You got the point fast!

Cheers, and stay safe.

This is a wake up call for many people.  I think we're going to see some pretty significant changes in Western lifestyle people.  Facing mortality is just a first step.

Shall we put our little gracy cells together and see if we can predict those changes?

Less or more risk taking? "I could be dead from a virus in two weeks.  Yeah, give me that rock climbing gear."

"Money in the stock market?  It all just runs away when times get tough."


Eating meat?

Will we move our manufacturing base back to this country? 

Political winners / losers?

Without knowing what the LR1 governor is like, Id also suggest looking at the governor.

My CS roid was doing the same thing and watching how it worked, I could see a spot where it was grabbing and wasn't moving freely all the way though it's travel. I bent it  to adjust it and got it running fine.
About a week after I did it I came across a vid on YT explaining how to do exactly what I worked out.  Clearly a common Problem.

Just look at the angles and travel of the governor if it's the spring compensated type and check the motion of it.  If there is any snatch points.

Also I seem to remember some people put a 2nd spring on the opposite side to stop the hunting and provide more resistance on some Governors.
I know on a lot of small engines there are 2 Springs that run parallel. The second finer one is just to take the slack and movement out of the main spring. I have a Mower I use for dragging things round the yard that has that spring missing.  The thing hunts like Buggery at low revs but is fine up top.

Might pay to search YT for your problem and see what comes up.

How did it sound when it was running?

If the timing was advanced enough to crack the piston, I think you would have heard it.  Would have been a metallic ringing sound.
The fact it didn't alert you makes me think it wasn't that bad and probably just a shithouse piston.

I did once play with the timing on my truck and set it too far advanced and the thing ran about 5 seconds before I could tell  it was off.
Also run too much Meth in the water injection which causes premature ignition and you sure as ship don't miss that either.

If you did load the engine and it was far enough advanced to cause damage, I also would bet you would notice a power loss because  the piston  would be getting hammered down when it was trying to go up. Probably would have thrown the piston in the bore opposite the thrust side and made a pronounced  rattle/ ringing.  I can't see how you would have not picked up something was wrong if it was that bad.

Veg is pretty Docile stuff and burns pretty slow anyway. If you dropped the compression that may have been enough to counter the timing  problem.  You can't have too much compression with veg either.   :)

  I think if the piston was getting hammered enough to break it,you would have well and truly realised something was amiss. Probably would have required a bit more speed to get the thing to fire and been prone to kicking back a lot -if- the timing was advanced enough to cause damage.  As you didn't notice anything for a week, my guess is that you got a crook piston. 
The advanced timing - may- have brought on premature failure but even if things were fine, I'd suggest it was doomed in a month or 3 anyway.

As my father is want to say, " Just because it's new, doesn't mean it's good"

I have plenty of first hand experience to prove that's VERY true and when  dealing with China/ India parts.....  Be more like  " If it is good you are lucky".

Well done on getting it running again. The first thing I would look at is the governor to sort out the "hunting" on the revs.

Firstly, thankyou for all your very useful advice. Much appreciated.

I had the bottom surface of the cylinder machined to the correct and original tolerances and re-assembled the engine with a re-con fuel pump and injector. I checked the bump-clearance which is now 'bang-on'

After priming the fuel system the engine started first time ! Whoop !

It runs fine, but it seems to be 'hunting' - slow and fast, slow and fast.

Any ideas?

Got to admit I am pretty worried about this. Been looking at some vids from qualified and experienced Doctors on this and whom the most suseptable are NOT to make it.
That's me.
My complications make my odds of getting though it even if there is all the care I need available... which there is a good chance there won't be. Then again, they say only the good die young so being the bastard I am, I should be here till I'm 150.

If my father gets it, no chance in hell he'll pull through it.  He has asthma and has had Pneumonia before and it kicks the shit out of him.  He also has recently Diagnosed heart problems. The local butchershop hospital for the region are less than useless at the best of times.  He lives in a place where there are more probably over '70s than 60 or anyone else.  Told me yesterday that there had been cases in his town and the next.  That's what they know of so far of course let alone whom it has and will be passed onto.
Only 3 people in the world I really give a shit about or can hurt me now and he's one of them.

Never thought I was going to see old age but might be over even quicker than I assumed.  Few years back I wouldn't have cared if I lived or died, in fact I stacked the odds against my self many times but nothing ever happened even though I well set it up to so I figured I was meant to stay around.
 Now, I'd like to go a bit longer although I know if that happens there will still be so much more heartache and pain in store as there has been my whole cursed life.

Might be time to have a talk to the daughter if things come to the worst and write some notes.  Maybe if I do that I won't need them bit if I don't.....

Still, my early demise wouldn't  exactly break everyone's heart.
Always figured with a history of cancer on both sides of the family, that would be how I'd go. Already got a list of scores I'm going to settle big time in my final weeks if that happens. 

Hope I don't get cheated out of that last bit of satisfaction and I do get through this.
Wife and daughter will be OK if they get it but if they do, it will be game over for me.

In automotive diesels I think cracked pistons tend to be from trauma?

For example, our Fonterra fleet experimented with LPG-fuelled diesel engines years ago - they went like the clappers but cracked pistons were the result

I wonder if having the injection timing substantially wrong could add "load" or "shock" to combustion forces?

Better-educated brains than mine will know

Would be interesting to have a sample of that cracked piston shot with an XRF to see what the composition of the metal alloy is.

As in China may back yard foundry's cast parts from a common mold, so there's absolutely no quality control.

This video shows people in China working their backyard foundry's just look at the type of scrap metals being brought in by the peasants.

The video below the first one  shows a backyard foundry in India.
