need dizzy expert
 

after learning that the aluminium dizzy and the cast steel dizzy have rotor and cap that do not interchange , i have an even deeper mystery ,, i have 2 dizzy both have the 0231 121 005 but the markings are different

1 has marking on the tag that says made in germany and on the body near the connector there is a marking that say ( 5 degree v OT) written vertically

the other has a tag that says germany then under ( importe d allemagne) in french but there is no marking near the connector

its for an original 914-6 , which one is better and why

thanks in advance

I'm no expert but what engine is involved?

its for an original 914-6 engine , rebuilt to factory spec 100% original , and once you recomend , i would really like to know why one or the other and what the difference between the two

maybe start with researching the ignition curve of each until you sort out the housing?

also maybe the carb engine dizzy came with a vacuum advance or no vacuum pot and the fuel injection came with a vacuum retard?

guys read the info before replying

the advance curve , I have it and its the closest you get to an original-6
the advance curve again , its the same part# , therefore the same curve
both have a centifugal avance , again same part number

why is the marking different, one in english the other in french and what does the 5 degree vOT means,

i know about TDC but v OT, on the english label one

i would try them both , but in a -6 its a big B to swap unless you are some sort of 4 arm troll!!!!!!
