Thanks again Martyn,
I have tried to listen for the injector creak but as yet have not heard it, the noise from the starting system winding gear overcomes it, I am waiting till I can get one of my sons to turn it while I listen with a 'mechanics' stethoscope.
I have seen a decent spray from the injector when it is in open air, but obviously do know if this is so, when in the cylinder and under full compression pressure.
I had the injector apart today, to be honest it was pretty clean inside.
If I do hear the 'creak' I will start looking elsewhere, I suppose after a 24 year sleep the rings might have stuck in their grooves, I am going to run it with a little red in the oil and some Forte engine flush to see if this will free them up (if they are stuck at all).
I will have to get it started with some Easy Start, then disconnect and look at the breather pipe to see if it is a heavy breather, this should tell me whether the rings are stuck and if it is letting gases by.
The engine does feel like it has very good compression though, I have reset the valve clearances to 0.006" (should be 0.004" but I prefer them a little on the wide side).
This engine has done very little work as it was vandalised and unused from about 7 years old, I am pretty sure the injector pump has never been fiddled with, so timing etc should be OK, when it finally does run, it is fine, no misfiring or smoke, it is a constant rpm model (2,200rpm) when I disconnect the rpm control it will go right down to a very slow idle, and stay there, not missing a beat, pick up is immediate without hesitation up to 2,200 rpm.
It is just the very hard starting problem whether hot or cold.
It has fresh red diesel in the tank, brand new in-line filter, new air filter.
Is there anything I have missed?
I won't be giving up on it, I need the roller to be reliable before the self build starts.
I thank you for your thoughts.
