I'm having lack of vacuum problems with my L-78. I'm in the process of fine tuning the motor for max vacuum, but I'm also tossing around the idea of a cam change. I have a thread over on TC and those guys are a great help. I'm wondering if anyone has the cam specs for an original L-78 cam. If I do decide to change the cam, I will probably wait until the end of the season, but for now I'm trying to get an idea of where to go with this cam/vacuum thing...
