Also you say you have checked the timing but have you checked the dizzy is timed with a timing light to the crank? If this is out it will also slow the engine cycle down
Definitely don't give up mate you will get there 👍

Took off earth straps to body and gearbox bracket and battery terminals and gave everything a good going over with sandpaper and new nuts etc. Much better 👍
I'm at a loss to be honest - big thanks to Nicci21paul for telephone assistance.
Basically I'll have to get a mobile mechanic in now - there's no attempt at firing at all. I haven't the time to spend on it now and not exactly earning browny points with wife spending hours with head under bonnet with no results. I wanted it on road for June.
I've got a spark (checked with plugs out and arking good), I've got fuel into chambers (no plugs in) when you lift meter plate and crank it, fuel spray comes out of plug sockets.
When it's all back together - nothing ! 🤷🏼♂️ Not even misfire. Tried "Start ya Bas…d" in inlet manifold - no difference.
Plugs are bone dry after attempt at firing - so fuel can't be getting in when cranking with it put together - end of ? So it's going back to original post that there a fuel delivery issue I guess.
I've tried several dizzi caps, rotar arms & leads, another coil, another spark module thing, I've gone back to timing umpteen times. Fuel pump running ok, fuel pressure at 5th injector and fuel filter.
So that's where I'm at presently .😞

Now I'm getting 4 bar on each cylinder so therein lies the problem. Off with its head then but I'll take it and get it sorted as not in position both time & knowledge to sort it.
There's a few other jobs they can do for me to finish resto off whilst they have access to ramp.

The trouble with doing nothing is that you never know when you are finished.

I'll check clearances whilst it's off and see what they read as

I did squirt a generous spot of WD40 down the bores some time ago - AND (whether I'm imagining it) their is a whiff of fuel on the dipstick.
Whether these can be freed off without taking head off - any solutions ? Guess oil down the bores may help.

Put oil in bores and redid compression test - this pushed it up to over 100psi. Left it a while and tried starting it again - still no joy.
Popped a couple more cc of oil in bores, refitted plugs and went straight to ignition key where it started almost 1st crank of the starter 🙏☺️. It ran very well although a little high revving - all that needs setting up yet.
So defo 4 stuck in piston rings (IMHO) causing lack of compression, which isn't surprising as engine been lift for almost 5.5 years without activity.
Question is what's best to leave in bores to soak rather than invasive surgery. Someone mentioned auto gearbox fluid, plus brake cleaner has been mentioned.
I've only had some WD40 in there and clean engine oil - nothing else yet as want to be sure.
I did think about a length of wood dowling through the plug holes and tap the tops of the pistons with my rubber mallet to shock them 🤷🏼♂️.
Anyhow a giant leap forward !!

When you have it running again check for vacuum leaks, spray WD40 around the inlet /air ancillaries and see if the engine speed changes, this can be a cause of high idle
