my Hot Start is now sorted.......
The Vacuum Retard on the Distributor is still an issue....
With the Air Con on it is cut out at all times ... but with normal driving it is fully operational with high vacuum especially at idle. And cuts out as the vacuum drops on acceleration.
But is the ignition still being retarded, say at cruise, when the vacuum rises again ???
Is engine load, via vacuum , always determining the advance curve by retarding as we drive ??? And thus effecting fuel...
