right had the 172 for a couple of months now - 1700 miles, filled up last night (was just below quarter of a tank) with super unleaded, went in paid came out turned her over and that was all she did - just span over after about 3 secs stopped, tried again and she started no problem. Left to go to work this moning and exactly the same happened, got to work turned her off and she started up fine (3 times), any ideas, looks like I may be experimenting with my warranty soon! Anyone recommendations for dealers in Kent (import), specifically Maidstone, Medway way?
