Heavier weights, or springs?
The earlier you can bring in the mechanical advance, the better. The advance should be all in by no later than 3000 rpm in most cases. If you used heavier springs, that's going in the wrong direction unless
you were having detonation.
Did you read the link I gave you on timing? ANY good timing info will do, it doesn't need to come from here.
Get the timing sorted out first, THEN the carb.
