Quote: Three of my local parts stores can not get the standard timing light and/or the correct timing tape, so I went to Summit to review their timing lights and I found one that is a dial back that is "Multi-Spark compatible" for $60. I like this unit because I don't want to mess with the tape and I like my current dial back but it won't read correctly. What do you think about the dial back that is MS compatible? http://www.summitracing.com/parts/EQU-3555/
