no power on take off!
 

Hello! I just bought a 92 campy le today it has 152k and I plan to do most of the work it may need! I need some trouble shooting ideas. When at a stop my take off barely has any power when i press the gas but when i get up speed the response is the way it should be. I can go into low gear and it works fine but in drive it feels like i press the pedal to the floor and it takes a while to get to 20 mph. I was stopped at the bottom of a hill and it would never go past 10 mph up it. I had the oil changed the trans serviced and new belts put on, any advice on this would be helpful! Thanks for your time!
