Hi Justin,
Mark Harding’s details:

just across Exmoor…
Before embarking on the journey, a couple of things you might do, which are also listed in other posts recently, if you are minded to poke around and have fiddle
– check for air leaks in the fuel line and around the carb gaskets.
– check for fuel line blockages
– have a look inside the float chamber – is the float sticking / sinking – is there any solid stuff floating / sinking in the float chamber that needs wiping out?
– is the little tube that drains the inlet manifold clear but not loose?
