Hi once again...Sorry ..I was not being sarcastic ..just genuinely trying to point in the right direction....The Distributor Doctor may be able to convert your dizzy to correct speck ..also correct carbs and dizzies turn up on Ebay quite often...if it looks the same or was fitted to a more upmarket vehicle itdoes not necessarily follow that it will work! If you want to improve performance its often best to try and start withe the motor " as per the book " to get it running correctly to give you base line for any modifications ...anyways.. Good luck with it!
