Hi guys, I've been reading a lot the last 5 days and I would like to thank you all for teh information .. it has been extremely useful.

W108 1972 280SE 4.5L

My problem:

Installed Pertronix 91885 (Ignitor II & Flamethrower II) -; red to (+), blck to (-) on coil.. and ignition 12V (before resistance) to coil (+)
Removed MB system.
Check resistance from dist. plate to batery - and had 0.2ohms which is correct.
Voltage to coil is 12V with switch to on position.
Spark plug cables are Bosch Ultra.... cooper wires (which AFAIK are not solid core, but im not completely sure)

Set TDC at cyl 1 and 0 at crank. made sure is at compression. (remove cover and align cam marks)
I removed distributor (0231402002) to clean and install ignitor and reinstalled with rotor aligned to lip mark and made sure spark cables are set accordingly to fire order.

Car was working ok with points.

Now Car wont start!!! ...If I rotate distributor to extreme CCW it would start barely, but I run out of the location screw.

I tried reinstalling with one tooth of rotor either way but it doesn't work.

Should I use iginitor I instead?

Any ideas?

Should i reinstall distributor with Crank at 10ATDC? or 10 BTDC? .. or it should always go in at 0 TDC?

PS: The black rotor seats lower than ignitor module .. not leveled on top. (guys at pertronix said not to worry .. ?¿?)

Merry christmas
