I think we may have overlooked something here... What fuel is it running? If it is E10 then you could very well have vapour issues thanks to the E10 boiling over at a much lower temperature than petrol. 7/900s have very hot engine bays when they're up to temperature. The old Bentley's I worked on would have an overflow pipe for the carbs, if you had to road test them for a service and then drain the oil while hot you would often get ethanol dripping on you and that was on E5!

In fact I've never done anything other than turn the key on a hot car.

My Turbo seems to run really well on Esso 99 as well. Much better than on BP or Shell

Weber carb. It sits on a plastic heat sink spacer and the pump is mechanical.

http://www.southerncarbs.co.uk/onlin...cessories.html Couldn't find the thermal gasket so if you contact them, they should be able to help with your 38DGAS carb. Alternatively i just remembered these people and here's the item that is most likely to help : https://www.burtonpower.com/carb-bas...nto-fv766.html Also check your air cleaner inlet, certain Fords had a snout on them that could be rotated for winter and summer to inhale warm or cold air respectively. Usually it pointed downwards over the exhaust manifold for the hot air in winter position and faced forwards for summer. Definitely worth running on 98 octane unleaded, the Essex wasn't really built for anything less than 4 star which is what 98 Super Unleaded replaces.

That was a problem in the 1980s as well so not fuel .. The volvo 440 with a twin choke downdraught carburettor has a small fan which blew air over the carb for about half an hour when you turned it off to prevent that problem .
