Car, Vitesse 2L Mk1, ran fine before I went on holiday for two weeks, took it out yesterday after a few miles started misfiring and engine cutting and back firing didn't think I was going to get home. No work done on car since previous run, less than a thousand miles since having the head converted to unleaded, seat inserts, bronze valve guides, as recommended, etc, distributor hasn't moved and no petrol bought since previous run.
So sticking valve, ignition component just starting to fail, something blocking fuel to carbs who knows but I think I will start by checking cards are clean unless someone has a better idea.
Joys of classic motoring.
Regards
Paul.
