<x-charset windows-1255>Hi, Thanks, Dave and everyone else, for your advice on timing. I read yesterday that the stock static timing settings are based on the assumption that you are using 90 octane petrol. This, I suppose, is what was available in the US at the time. Over here, I am using 96 octane leaded fuel, the only type of leaded fuel still available here. This is soon to be taken off the market here too, so I will be left the with choice of 95 or 98 octane lead-free petrol. Anyway, how should I expect the more potent petrol to affect the timing? No, I didn't remove the vacuum hose. I only saw this mentioned as necessary for later engines. While on the subject of petrol, does anyone have any experience with the additives used in leadfree fuel in old engines to simulate lead? I know the proper solution is to change the valves so the car can use leadfree fuel, but I need something I can use until I do that.
