sorry i missed the new coil didnt work bit. 
The only thing i can think of ignition wise in the distributer is the points and this condenser
Manual says faulty condenser = poor starting and uneven running and yours hasnt got one 
I would get one and try it as its a cheap part to replace.


just thought check those little vacuum pipes behind the carb for any not connected properly or split
for when you get it going
