So that I can fully understand the problem can you please provide the following information.
When the pilot pushes forward cyclic which way does the swash plate tip?
What is the lead angle of the pitch horn in relation to the blade?
Here are a few examples so that you understand the questions.
On Bell single rotor helicopters the swash plate tips down over the nose in line with the longitudinal axis and the pitch horn leads the blade by 90-degrees. On other Bell single rotor helicopters the swashplate tips down towards the tail and the pitch horn trails the blade by 90-degrees.
On the Robinson the swashplate tips down over the nose in line with the longitudinal axis and the pitch horn leads the blade by 72-degrees.
On a Sikorsky helicopter the swashplate tips down 45-degrees ahead of the longitudinal axis and the pitch horn leads the blade by 45-degrees.
