95 octane problems
Just a quick question about running 6 cyl cars on today's petrol. I have just bought back my old vitesse engined Spartan kit car and am getting it ready for the road again after a 13 year layoff. I recall that the last time I ran it (1995) it was susceptible to pinking and needed the timing retarding a bit. Have any of you 6 cylinder sammio owners had the same problem and if so have you discovered a better solution?
