Hi James

This symptom is one of many we've encountered in the pursuit of the
ideal performance. There're a lot of things we can do about it, and
yes, it sounds like fuelling, although it may be related to how your
distributor's vacuum advance is plumbed up. Renault and Volvo did it
differently. There's more to fuel adjustment than the mixture screw,
specifically related to vacuum enrichment - and from what you're
saying, it may well be in your interested to re-install the DeLorean
CPR with a different vac plumbing. Pop over sometime
