If its a motorcraft dizzy your running, put dizzy internals at full advance then put spot weld on plate so its locked at full advance then set point gap then set ignition timing. I found xflows with a motorcraft distributor, decent cam and compression respond better by locking dwell angle at full advance and disconnecting the vacuum advance altogether, or get an early xflow lucas dizzy and use that. Can use mini lucas dizzy by removing gear on bottom and putting a xflow gear on shaft. if your xflow motor has been tuned a bit set your timing to static marks or with light then advance timing slowly til revs rise then when revs stumble back off touch then lock dizzy.. If u need some bits to fix your dizzy I got some lucas and motorcraft dizzys in a box in my shed somewhere.

Mate I live at waihi beach, if you have no joy with local mechanics I can have a look if you want, Ive mucked around with webers for years. they pretty basic and I got a box of weber carbs and parts sittin under my bench. is it for the white mk2 4 door at the beach? pm me if want me to have look at yor car. Also mate check your point gap, cant remember exact gap clearance but crossflows point gap always tends to close when given a bit of stick and give symptoms you described when under load

Hey mate, if you want to sell the sump and pickup Im keen to buy it, Ive built a few of these engines, I used Vauxhall chevette valve springs, acl 1300 pistons with smaller dish up to 60thou, polished castings off conrods and balanced big end then small end on digital scales and set weight of all 4 to lightest rod, 1100 flywheel, 234 or 244 cam and always a 711m block. Cool engines and cheap to build by using parts from other models and engines.
