I was out in the garage last night with my 76B and thought I would check the timing, so I got out my Haynes book and my MG service manual, maybe it's just me or I wasn't looking at things right, but the Haynes manual shows the 20 degree mark on the far right tooth and the MG manual shows it as the far left tooth.... can anyone clarify this for me? Also I've seen different timing for different rpm's, is it 1/2 of one and six of the other? Or does it make a difference? I realise the need to set the timing mark for the correct rpm, for instance it might say 12 degrees at 600rpm or 13 degrees at 1500rpm MACK /ubbthreads/images/graemlins/cheers.gif
