Spitfire spitfire 1500 refuses to awake after 10 years

Hi
I am trying to help my son get a spitfire 1500 running after a 10 year hibernation but it refuses to play.
When we first got it we drained all fluids and fuel, replaced fuel lines/pump, rebuilt carbs (removed waxstats for alternate type), all new ignition components (plugs,points,condenser, coil,leads) and gapped the tappets. We also checked compression (155/155/155/125 psi, although number 4 did come upot 140 after oiling the bore so may be just stuck ring. We set static timing to 10 degrees before tdc at the point the plugs open for Cyl 1. For the inital carb. set-up the jets are 2 full turns below bridge level and the slow running screw is 1.5 turns after it begins to move the butterfly

It would fire but only run roughly for a short period at high revs on the choke and immediatley die upon opening the throttle. This was exactly the same as before we did all the work.

I assumed we had an inlet manifold leak since there seemed to be plenty of fuel at the carbs (albeit a large vapour lock in the in line fuel filter) so we replaced the manifold. No change.

Having now rechecked fuel flow (good to carbs but still vapour lock in filter), timing, plug lead order and swapped back to old coil it refuses point blank to play. After cranking on the starter for ~5 secs it will fire to disengage starter but not run on. Even a healthy dose of damp start would not elicit any response. Having re checked compression we seem to be down to 60 on cycl 4 but that may be due more to a low battery and slow cranking speed. The plugs seem wet/oily now upon checking but there seems to be a weak spark when held against the engine.

Any insights/ideas greatly appreciated because I am all out of ideas.

Many thanks

Ian

Ian,
You posted your question in the "Triumph Classifieds" forum.
I suggest you repost your question in the "Triumph section" and I know you will get the help you require.

There are lots of fittings in Triumph intakes. It only takes one open to make the mixture grossly lean If all the vacumn ports do not have a hose connected to each one that could be your problem.
