Any ideas.

Vapor lock. Next time it happens, pull out the choke and then try starting.

John,

This is currently a problem with my colleagues MG PA. He is bringing it to work nearly everyday and it is suffering from vapour lock equally. He already has silvered manifolds which are reputed to work (which I doubt) and he is currently constructing a heat shield. Tomorrow we will see if he has succeeded! If I can persuade myself to take one of mine, maybe I will have the same problem...

The other thing I've done is to mount the carbs on fiber blocks much like an MGA. This provides a bit of distance and heat isolation between the carbs and the intake manifold.

Try a dash of diesel in the fuel tank - I use about 1:20,

contact set gap- it was too wide on Talbot and I got stuck in several embarassing places- fortunately I was always found someone to push me (and get lots of teasing- best was from some taxi drivers at the railway station) til I realised what it was

John;

Try loosing the fuel pump fitting on the carburetor side to burp the fuel line. It works for me on both the 12/4 Kestrel and the Big 4 Special. Insulated spacers between the carburetor and the manifold also help if you have room to clear the bonnet.
