[QUOTE="Don Morris, post: 149773, member: 4564"] Martyn is right, the thread is 3/4" x 20 tpi, which is a Whitworth thread, "Special". I use an E80, hollow axle nut, to clamp the timing disc. The bolt is a plain piece of rod which was part threaded by a friend, this was many years ago. The Thorspark has no contact breaker, you are forced to use any marks to guide you, from the supplier these are felt pen marks, and then check with a strobe. Thinking forward if I satisfactory time up OK I will mark up the rotor and mag housing this and my piston stop, a plug type body with a fixed rod sticking out which hits the piston (carefully) at the desired timing point.. Useful if your timing slips while you are out on the road, and setting up the timing disc at home. I have manual advance and retard by the way, I look back, with some nostalgia, to the fag paper.
