Yes its the original type of arm....
The table is leveled, the cartridges are setup with proper tracking force using a digital scale and I have not noticed any problem when the cart is traversing in the runout groove.
The silicone is of the correct consistency, that is why the idea that maybe the lower paddle might need to be submerged in less silicone so that there might be less resistance to horizontal movement seems to me as a possible cause.
I sent a message to Mike Pranka, but have not received a response yet.
I have digital copies of the tonearm setup instructions, I will read them again, maybe there is some helpful info there.
