Sorry gents I should know this one, have trolled the Lucas mails with no luck, can't believe it's not been asked before though.
With the timing set up as per Haynes - Timing side pot on compression, points set with the heel engaging the bottom cam which pickup provides the spark?
I'm at the stage of fitting the plug leads, and would appreciate your help to save a bit of time.
Thought I would have the thing up and running yesterday but first off I lost the rocker box covers, took a complete shed tidy up to reveal them.
Next I had forgotten to wire up a kill switch, then the Indian Fuel tank proved to be not quite correct in the single bolt fixing area, also found that despite the fine spline on both ends of the rear brake cross shaft it proved impossible to get a position to suit the cable although the answer is most likely to do with the brake linings as there is a bit too much travel on the arm

Hello, always wondered about it, but always after the mag was back on the engine! Having the magneto in front of me this time, turning by hand and looking at the safety screw spark, occurs at the opposite pickup relative to the points - Or said another way, at the pickup closest to the heel\cam.

Once the mag is mounted on the bike, you'll need a small mirror, placed between the cylinder and the front pickup opening, plus a torch. This way you can spot the brass insert on the slip ring.

Many thanks guys - now if I remember, I'll print this off and insert it into manual

Set the magneto so that the points are just opening at about the 10 o'clock position. The HT lead from the rear pick up should go to the right hand side cylinder as you are sat on the bike.

Thanks Beezageezauk, thats what I'm after

I put a couple of dabs of white paint on the plate the points are mounted on to indicate the extent and location of the brass contact. Saves me having to get my dentists mirror out for next time.
