I've forgotten exactly how the distributor shaft goes, but maybe that's loose... I recall there's a bevel gear that's driven off the intermediate balance shaft... that may be loose somehow, allowing distributor shaft and the rotor to move up too tightly against the contact on the distributor cap... For my Franken-motor, I had to replace the distributor shaft bevel drive gear with one that fits the ABA (2.0 l) intermediate balance shaft... That allowed me to keep my Digifant distributor (from the 1.8l inline ) and not change anything else from the Vanagon electrics or wiring harness, or the head, and keep the body stock.. Didn't even have to re-time it.. I don't remember if you took all that stuff apart during your ABA install... Could be something to consider
