I know it's been 10 years since I last owned a 914, 1973 914. But I have also owned a 1971 and 1974 914 over the past 25 years. And I remember that the rotor inside the distributor points to the mark on the metal case indicates cylinder #1, and typically that would be around 11 o clock if you looking down towards the front of the car.
However, in this 912E (2.0 Type 4) motor I have the mark and rotor are at about the 2 o clock position. Here is a link to a video I did on what I was tuning up the motor early this year. The car seems to run great, does get a bit too hot (Summer in Phoenix Arizona).
I was chatting with another 914 owner this week and he confirmed that on his car with a 009 and carbs that #1 was at about the 11 o clock position on his motor as well.
Just wanted to see if the 912E version was different or is this thing running on magic!? LOL
