Default ICU-P ignition Ver.2 (custumized version?)

Hi, I've bought a second hand MVVS 45 IRS MG engine. Engine is supplied with a very strange version on Ignition unit! Ignition unit is the ICU-P (professional) Version 2 but it is supplied with plug cup suitable for M14 Brisk spark ! (in my engine is installed a Brisk U17 with M14 thread).

I have tested the engine on the bench and seems to be regular.
Question is: is my ICU-P with big spark plug cup a customized version ? Because all ICU-P ignition that I’ve seen on the web are supplied with spark plug for NGK M10 plug.
Very strange for me!

Any advise ?

Thank you in advance, regards.

MVVS supplies conversion units, so old Vlach (M14) systems can be changed to the new ICU ignitions.
According to MVVS, the systems with M14 plug boot are made to work with the magnets at 180 degrees apart, so no change of prop drive is required.

Thanks Pe.
Please note that my propeller drive washer have two magnets at 240° (not 180° as stated by you). Is this correct ?

All ICU ignitions with M14 plug boot work with the magnets at 180 degrees.
I have to ask MVVS if 120 degree magnets will be a long term problem. The ignition works OK with them, or so it seems.
