Have a 2e in a boxy here and it starts and runs...but only if I hold the key between on and start once I let the key go it just cuts out... Wiring wasnt touched as car lay up and tried changing the following Carb Dizzy Dizzy cap Condensor Fuel pump Leads Plugs Checked timing and ignition timing .... I'm at a loss here is there any earths or plugs that cause this issue that I may have missed!
