Hi Steve, i would suggest that the depth mesh position of the distributor needs checking. The gear needs to be in the correct vertical position relative to the centre line of the gear on the dynamo armature. This is controlled by the 'length' from the centre of the teeth to the underside of the clamp that mounts the distributor to the top of the dynamo. This clamp position is in turn controlled by the shoulder on the distributor body that is formed by the end of the machining of the distributor body outer diameter. This distance needs checking against a standard Lucas distributor. I have not used bosch unit for this (and many other) reason for a very long time so don't have a clear memory if they are interchangable. I have, however recently set up an aftermarket distributor made for a VW type 1 installation, and this distance would have needed significant correction, had i simply installed the A7 gear using the cross pin hole for the VW drive coupling......My dynamo housing may be non-standard though.....W
