hi, i just bought a 1982 vw golf cabriolet for the summer(if we get one!) it looks, sounds, and drives superb and i'm chuffed to bits with it. However one thing niggling me!  The car starts first time when its been sat overnight, but when its been driven for a while, it decides to take about 10 seconds of continuous key turn to fire up! since i nothing about engines what so ever, i am looking for some guidance before i go to a local garage and get ripped off! Anybody point me in the right direction??   Many thanks   kenny
