Easy as 1 2 3, Got it yesterday, pushed all projects aside! Options

Got the 123Ignition yesterday, I pushed all of my projects back!
"Sorry granny I'll get to those bearings on your heart/lung machine soon, I promise."
Blocked out 3 hours for the removal and install.
Added about an hour to charge the battery.
Installed as expected, there is a spacer that is necessary for type 4, just slides over the dizzy shaft.
I decided to route the wires and vacuum away from the fan so access to the vacuum nipple was easier, since the vacuum can is gone there's a lot more space.
Followed the instructions but made the mistake of using the TDC 0* instead of the 27* as the basic timing point. I just walked the dizzy CCW until she started!
Didn't do anything other than matched my timing with my idle, I let her run till she settled down.
Just around the block once, ha ha the trailer hitching is GONE!
Responsive throttle, man!
Setting up a tuning session, nice 150 mile run up the California coast with the AFR meter.

I took her out for an early spin on Saturday, 68*F ran like "Jeckell" BOY HOUDY...

Using up the last 3 gals of the 94 octane, mostly 14 fwy, 85 mph uphill

I decided to remove the vacuum retard hose and cap the throttle body, I did have idle issues. I tried to get the best balance between day and night, driving lights off and on.

I seem to have an issue with "hot start," five to ten minutes in a store to pick up something and wham.
My usual procedure is to press the throttle and feed some air, but that was not working. Getting the engine to start was a bit more difficult. I needed to floor the accelorator pedal holding it until the engine fired and than feathering the pedal so the engine wouldn't stall, not what I call ideal. But after a minute or two a stable idle.

Ok after a good 60 + mile ride, time for fuel. Second Wind sugested Chevron premium 91 octane, as a good quality gas, so 8 gals of 91, outside temps low 80's*F.
Out of the station and right onto the freeway on ramp, and floored the accelorator and wham, ping, lots of it!

So immediately there is a change, it is directly related to the octane of the fuel.
Next test is to drive in a lower temperature environment to see it the ping is present at mid 60's*F.
I'm going to wait till the moisture clears up a bit here in Los Angeles as a storm moves through.


What I may need here is some advise as to what I can do to run without ping using pump fuel.
I'm in L.A. it's a good 30 mile trek to get some of the 100 octane "race fuel" and real fuel additives as octane boosters are not to be found on the shelves of the general flaps.

Of course the obvious is to reduce the timing a bit.

On the 1,2,3 I found that the cap could move around a bit and add a few degrees of timing to the problem just by knocking it about. Something to check for sure.

Also may want to check your compression to be sure that you have equal values across.
