[Fot] Ignition System Preferences?

[Jim Gray]

I've been using the 1-2-3 for six years and not a problem. It's the first
gen model where you change the programs with a screw pointer, not the USB
conx. type.

Back in 2005 or so we had a long discussion of distributor problems; broken
mechanical advance tabs, junk condensers, and expensive replacement parts on
the Mallory Dual Point units, worn out parts on Lucas units that therefore
became ammunition in catapult battles, short life spans and improper phasing
for the Pertronix Ignitors, misfires on the MSD units from low battery
charging, etc. I think the "123 Ignition" was just being introduced around
that time.

 

So a decade or so later, what have we learned? What's working well, and what
have you given up on? I'm needing to decide which way to go on my Spitfire.
I have a couple Mallory DP's lying about and several different Lucas units I
could send off for refurbishing. I've looked at the Pertronix with their rev
limiter box, and it seems intriguing. I've not heard much about the
Pertronix or the 123 systems in racing use.  Knowing what you now know -
what would you recommend and what would you steer clear of?

 

The Spitfire will have an 1147 this season, and a 1296 is to be built this
next winter. Both will run Kastner A6 cam grinds that I just got back from
Ted at TSI. I'd look at 7000 rpm as a limit for now. I'm almost completely
inexperienced in regards to working on ignition systems, so I'd like
something with a shorter learning curve and a good reputation for
reliability.
