Points vs Electronic ignition and Pulley timing mark

[Mark Towers]

Hi,

I'm currently running a Lucas distributor on my F60 LAAT. I'm considering purchasing an electronic crab distributor.

Question 1 ...... Can any one tell me the pros and cons of an electric dizzy

Question 2........ I believe my timing may be out a little, I'm looking for timing Marks to use a strobe timing aid .... I found a distinctive groove on the rear pulley wheel on the double pulley this morning ... the middle and front pulley wheels don't have the distinctive groove on them ... only the rear . Is this a timing mark or just a large chip ?

I appreciate any advise

Kind regards

Mark
