Thanks for your usual quick replies. I thought that the direction of rotation would not matter too much but I've just taken the one off the Chummy it was destined for and the direction of the Rotor Arm is the same but it 'sparks' quite well if the Mag. drive is rotated clockwise but not at all if spun in the opposite direction. opposite to the one that's just been rebuilt. Points to some sort of internal shenanigans that's beyond me! The chap who rebuilt is very experienced and seems to think it is the cam that's at fault but I'm not sure why. By re-timing, Stuart and Stev, do you mean taking the main gear off and altering its position to smaller one ? I would've thought that no matter what its position, it should spark in a clockwise direction.
