More stuffdone

Hi all,
i am in the process of acquiring a ST1 with a rather odd serial number prefix....

MY 64 ST1 81 06

can anyone enlighten me the prefix MY?

i am writing from Malaysia and as far as i know, only the 8/1 and 16/2 were CKD here.

meanwhile, can anyone let me know the dimension of the 4 mounting holes at the base?

your input would be much appreciated. thanks!

At a guess - it's an export marker; "MY" does rather suggest "Malay" i.e. Malaysia, doesn't it?

Looks to be a 1981 engine (I think the "81" is actually "31", with some somewhat heavy-handed stamping), I'm not sure what the "06" suffix is - could be the build number (which appeared officially on the plate from 1982).

There is still a little bit of grey haze but I think it's just a little unburned soot in the exhaust.

No diesel will run completely clean, there's always a tiny bit of smoke no matter what. It sounds like it's pretty well dialled in with the old injectors.

Lucas nozzles give MUCH more diesel than Bryce so the engine has drowned in diesel.

It's easy to be intelligent after the fact... I nearly replied to your original post suggesting overfuelling, since that was the only possible scenario I could think of which would produce white smoke AND power... normally, white smoke is a sign of failed ignition, rather than successful combustion of all the fuel & some left over! But... I wasn't confident enough to suggest it at the time...

I suspect you could use your Lucas injectors, but you'd need to work on the fuel pump(s) to reduce the amount of fuel injected. I'm not familiar with the TS engines, I believe with the CS engines this is achieved with shims (or is that timing? Someone correct me if I'm talking ballcocks).

I guess the other possible giveaway would be - are you getting a lot of fuel back through the leak-off pipes on the injectors? If so, that would also point to the fuel pump being unnecessarily generous. Just a thought - again, I don't know much (anything) about the TS engines, so just guessing there.

In sheer desperation I fished the old discarded Bryce nozzles out of my metal bucket yesterday.
I polished them with some scotch brite and fitted them in place of the new Lucas nozzles and adjusted them to 210 bar.
There was also a lot of carbon build up on them after they had only been tested for a maximum of 2 hours.
Then I fitted them in the engine and started it up.
Now it doesn't smoke white anymore.

I find it very strange that all List Petter dealers sell the nozzles as plug and play.
