A number of you posted that you installed a 123 distributor
from the Netherlands. Will, you did yours last fall.
Any long term feedback on your experience?
Iām going give Pertronix a 3rd try and if their lobe sensor
design still looses track and goes into shut-down, Iād like
to consider the 123 for my xk120.
Althought Iām generally happy with points, I did notice what
I thought to be an occasional misfire at sustained rpm over
4000. Iām hoping a modern type of ignition will cure that
problem.ā

I installed a Petronix in my xk120 last year I have taken it on a
few long runs and it seems to work well, however on two occasions
when I tried to restart after a run it would run rough and lumpy
for about 30 seconds and then be ok, it almost seemed that the
Distributor lost its timing or orientation before smoothing out and
then running fine. not quite sure what is happening. Would be
interested to know if others had similar things happen with the
Petronix System. I can always go back to the original Distributor.
āIām hoping a modern type of ignition will cure that problem.ā
Did for me; Mallory 18 years ago, and, āso farā, no problems.
Cheers,

Perhaps āheat soakā with āmodernā gasoline formulations. Have experienced āhot restartā symptoms in warm to hot weather where I drive (5,600 to 10,000+ feet) over the last 18 years (progressively) , seemingly coincident with efforts to reformulate gasoline; especially noted when stopping to refuel. Car will buck and chug for 20+ seconds driving away from pump. Now I idle and wait for ācoolā fuel to enter the carb before motoring off. Sometimes using choke (electrically operated on 670207) seems to help.

hmmmmnnnā¦just my two centsā¦
I have the stock distributor/points, as all the XKs have used for
years, and have had no problems, almost never touch it, maybe
cleaned up the points once or twice and replaced onceā¦this in the
past 12 yrs. Sounds like 'āsomeā of the improvements, may have
their own set of issues.ā

Michael,
I believe your issue is not ignition, but fuel. Nearly all of our vintage cars: ( '38 BMW 328, '52 Riley, 2 XK120s, Morris Minor, '37 Packard 120, and others), are all experiencing hard starts and rough running after driving and then sitting ( 20 - 30 minutes). From what Iāve read,ā¦Ethanol only makes the situation worse.
Cheers,
Knight________________________________

John ALL cars misfire!!! New state of the art cars misfire. The
fault programs do not activate with a single misfireāonly repeated
misfires on the same cylinder. My advice is to have your orig.
distributor rebuilt properly and it will work just as well as any
other system you are thinking about. Please remember that when your
120 was new Jaguar was having a bit of success in a 24 hour race or
so that was run on POINTS.ā

Rick,
Itāss too long before we shall meet again.
Miss: (1) wear good ear plugs. Mine cut the level by about
15db, and let some highs thru so I can still hear things
like gears whining etc. In fact it helps ones ability to
hear things like clacking valves because they filter out
the lows and mids.
(2) 90mph next to the concrete median - guard rail, you
can hear the occasional hiccup. I doubt I could hear it
without that reflecting barrier three feet away.ā

I installed one on a Porsche 356 three years ago. Easy to do, set up and no
problems so far.
No power increase, in some cases still misfire related by the Webers, but it
cured the hot starting problem 100%.
On the 120 is still use the original point distributor without any problems
in the Alpes. Popping only after lifting the throttle after a WOT period.
Best regards
Thomas

Hello,
I have a XK150 and a original S-type, both with a 123
ignition. Running fine for about 3 years now.
Did some testing with the settings, and ended on āā1āā
Good start always even after a long winter.
When engine is hot I just push the starter for a second, and
it runs.

Knight, et al,
I think the boys are still on their British Invasion, Vt. high.
I have a 123 in my 140 for past four years +. Excellent and
improved performance. I carry the spare, points dizzy just in case,
but so far, VERY reliable.
I have experienced pertronix failure in another, Ford powered, car.
My 140 also runs rough when started hot. I suspect vapor lock
caused by heat soak and crappy fuel rather than ignition issue.
Usually clears up in 10-20 seconds. Switching on choke till it
clears helps.

ps
Missed seeing the old gang at Stowe. Rick did call with a glowing
