The story
The old 4ac died so i did a swap for a reco'd one that came with an electronic dizzy, everything is wired up and running i even went and got a new radiator


The problem
when i turn the car off the engine the car wants to keep going. its getting to the point where i have to stall my car on purpose just to get the engine to stop


i did the tappets they're fine, timing light said it was fine, i ran a bottle of carby cleaner through with a full tank of unleaded.

what is the problem? spark plugs? ignition leads? carby settings?
any help would be much appreciated. because im outta ideas
