Perrymatic Jetstreme mk1 68k btu

Hi, anyone got any clue on settings for this boiler? I know it's touching 40 years old but apart from being horrendously inefficient, the customer loves it and is reliable.
I turned up and the previous engineer had left no paperwork or nozzles, and today was very sooty and dirty.
I've gone 0.65 80ES at 150psi with 10.5 CO2 fgt 259'C
What you lot think??

What CO figure did you get?

Why such a high pump pressure? Is it kero or gas oil?

Settings should be OK for gas oil but recommended to use a 0.65 80W. Same nozzle for kero but a pp of 125psi.

Its not that high imho. The older the machine the less tweaks it gets. A good clean, new nozzle and co2 checked then minute adjustments to oil or air to get somewhere near 10.5 co2. Then left alone for another 12 months.

Can't remember the CO reading, maybe about 70, def not more than 100.
I basically went off the settings for the mk2 (which I have) I know...... as rare as rocking horse muck
But didn't know if anyone on here had ever come across the papers for the mk1, if they even existed!

Yes, settings as above.
