If you car has Solex carburettors they have a weird choke setup (opposite to normal, instead of restricting air they add more fuel or something) which sounds horrid when used ... even scared the mechanics at my fathers workshop when I left my GTV there once.
Solution is to not to use the choke ... I never have, just 3 pumps and away you go.
