I experimented with my mechanical advance by buying a Moroso advance kit (weights and springs). I found the Moroso weights were lighter and the springs were not as strong as on the original stock HEI distributor.

If you have the original heavier weights and try using weaker after market springs the mechanical will come in very fast like you are experiencing. Do you have the original stock springs?
