i swapped the igniter today. I took out the old, and connected the wires for the new one. tried to start = same result - starts and dies immediately. I put the screws in to fasten the 'new to me' igniter in position and tried again. It started and ran a bit longer this time before it died. Again and it starts up and keeps running!!! I tapped on the gas and the engine would cut out immediately but keep running once i let go of the gas. i repeated this a few times and eventually got the engine revving by manually using the throttle cable. After this she died again and is currently as she was. Starts but dies immediately. So basically she ran once but didnt like it when i gave her any gas. Also i cant help but think this is something i have caused. As it was running prior to me changing the plugs. Is there some vacuum line or something i may have disconnected that is causing this?
