Hey savagejim or downunder i know that these post are old but reading them over and over and trying to duplicate what your saying to do is tougher than i could have imagined. i am not a stupid person but im feeling that way trying to time my mill out, when im measuring for HTOT on my crank am i measuring from the top of the crank or the top of the whachamacallit i dont know the actual name for it so i took this picture, from this info i can figure out the rest of the measurments because they pretty much start at the same spot except H1 is that the middle of the whole on the crank?? thanks in advance for the help.
