Austin Big Seven carburreter

[Ian Williams]

With 30VM's, in fact any high level carb and mechanical pump, I find a few strokes of the fuel pump priming lever usually gives an instant cold start, after that no issues. As Dave says a fully closed choke helps and it is also worth checking the idle circuit is clear, they can sometimes be blocked and cause problems. If you lack a priming lever a couple of turns on the handle prior to turning on the ignition will have the same result.
