there is a lot of ways to bake a cake and most woods port saw builders ,me included have posted oodles of pics and port timing numbers for people to try and replicate and not have the expense of sending it in. i get calls daily asking for hints and tips that i give away freely. woods saws are not holy grail un-obtainium becouse theres 1000's of them out there that have been tore down to see what makes them tick. now race saws are a whole other ball game and builders request that you never open the saw and give them first oppurtunity to buy it back if you sell becouse racing is about tenths of a second and once you rech a certain level of speed those other tenths are the hard ones to find and we sometimes garner those secrets very closely.
