It's comparatively easy to set the mixture close enough on twin SU's. Assuming plug gaps and timing are correct, the throttle shafts aren't leaking air and the pistons lift and drop cleanly, you can get them pretty close with the lifting pins.

Initially you want the air intake of each carb matched. You can use a piece of plastic pipe to listen and adjust if needed (throttle link loosen...

Ran engine this afternoon, got to 175 deg.
All seems ok.
Will re torque the head tomorrow.

I tend to agree with you Trev.

But with France shutting down a nuclear reactor because cooling waters may get too warm, whatever the cause, this kind of heat can't be shrugged off.

Just had another look and I can’t see how to remove what’s left of the broken quill.
Looks like a peg with the spring part of the quill attached over it. Can see it being a nightmare to try and reassemble as basically it’s inside a tube. Doesn’t look at all simple.

And so it begins.

I would think not rings as a neighbour had all 8 compression rings broken in his Ford Xflow Morgan and that still had about 1/2 normal compression.

If you have concerns I would just do a follow up oil and filter change after say 1000 miles.

If you really have zero compression I think it must be a stuck open valve.
Rings/bores would just give a low reading and a gasket would need a big blow by for zero.

Take out the plugs and turn it over by hand watching that no 4 cylinder valves go up and down fully.

Just to put all this temprature hype into perspective I read today that tomorrow is expected to beat the previous record of 36.3 set in 1976. That was exactly 50 years ago so hardly global warming and it proves what many of us oldies have said before that we have had hot summers in the past. In fact 76 had prolonged heat even in October. I remember it because I got married mid October and even the...

That is it: a quill

Used to get my gauges restored at Vintage Restorations, Tunbridge Wells, but, alas, another business closed.
