[QUOTE="greg brillus, post: 98742, member: 597"] Not necessarily........If it has been set up at a lower full advance figure of say 26 degrees, then the retarded position will be after TDC this is the starting issue he is having. You need to disconnect one coil, then reset the advance back up to 34/35 degrees. There is a small cap screw made of brass usually just behind the mounting flange, same spot as the earth brush on an original Lucas mag, unscrew and you need a short length say 75 mm long of 6 mm rod, you could use a drill I suppose. He would have to remove the ATD cover at the front of the timing cover, undo the pinion clamping bolt in the center of the pinion, set the crank on the firing stroke at 34 degrees BTDC and realign the mag shaft with the rod down the hole, re-tighten the pinion bolt, remove the 6 mm rod and button it all back up. It would be best to use a timing disc and pointer to get a more accurate timing figure. With that amount of advance the retarded (starting) point for the mag would be about 4 degrees before TDC, thus much better for engine starting. Cheers and good luck..............Greg. [/QUOTE]
