MG MGB Technical - Zenith Stromberg auto choke gasket

Just finished rebuilding choke on my Zenith Carb. Upon reassembly is sealant used on the gasket between the choke and carb?
JCH Hibbard

If the two halves being joined by the gasket contain coolant then I'd say yes. If not then I can't see it being needed. But in my exploded drawing I can't see a gasket, just a sealing ring between what looks like the water jacket and one side of the heat mass, presumably for the coolant.

Thanks Paul, I should have mentioned I removed the coolant jacket and am using a manual choke. Just not sure about reattaching the choke assembly with sealant.
JCH Hibbard

Can't see any need, then.
Paul Hunt

Unfortunately after reassembly the car won't start. I know the choke mechanism is working correctly and gas flow to the carb is good as I checked both. I replaced a cracked manifold a few weeks ago with another original and reinstalled the carb, choke was the last step before firing it up. Ran perfectly before, not sure about about this.

Check everything from first principles i.e. plugs smelling strongly of fuel if not wet after a period of cranking with no start, spark to each plug, and in the right order counting from No.1 at TDC on its compression stroke.
