I had this very problem and it pestered me for months. Checked
timing, checked condition of advance plate, yada yada. It turned out
to be fuel starvation, but from a very sneaky place. In my case ,
after Pat Horne came to the rescue, carbs were balanced, floats
adjusted etc. it turned out to be some obstruction in either the line
from the fuel bowl to the carb nossle, or the jet itself.
Try replacing the fuel filter to start with, see if that helps.
Other possibilities i looked into were:
Blocked fuel pickup in tank (blew out with air)
Fuel pump problems
Gunk in Little screens in banjo fittings at carbs.
Start with the fuel filter, see what happens.
