Oh yes... the octane. It seems here in the States, we have Regular - 87 octane, Mid - 89 octane, and Hi - 92 octane. I wish I could find the 97 octane. That may be the culprit. I have a new tank of the hi in it, and hope it fixes the run-on dieseling.
I'll have to learn what the Advance/Retard is on the distributor and find out what proper heat range plugs to use.
Thanks
Hi Vitruvius
I hope I do not repeat in a redundant way what someone else might has said (I haven´t read all comments very detailed)
When I visited your country two years ago I was wondering how all the Porsches etc. could run with just 93 octane maximum to be offered.
The solution is, you have different octane ratings:
In Europe RON, in the US AKI
97 RON = 92 AKI
