403 not starting

[peterg]

The car failed in an embarrssing way a couple of nights ago (second time).

Previously the electric fuel pump failed (two years old). Bypassed it and it ran on the mechanical pump. Fitted a new electric pump and it ran OK.

Then it stopped 'mid flight'. By passed it and primed the cars. Nothing, except the pump was working (forgot to disconnect it). Reconnected it, still nothing.

Checked the plugs and they are in good condition and sparking. Took the air manifold off and sniffed the carbs and could not smell petrol.

There is pressure in the supply line.

What could be happening?

Also, the middle carb isn't connected to the choke. It that normal? There is a hole in the linkage bar and a spring is connected to the arm but no linkage.
