OK, first off, I'm gonna assume this is a K-series problem as the wife's old 200 bubble used to do this. If I stall her, or I'm a bit to quick with the ignition key, she doesn't like restarting much, and turns over several times before firing properly. She doesn't do it if she's left for a couple of minutes (like when filling with petrol). So whats going on? Is it just new plugs time?
