There is only one timing mark on my 1.8 fan. It's visible through a notch on the rear side of the fan via the inspection port. Pelican parts info says the mark is TDC. Auto Atlanta says it's 7.5 degrees BTDC in the 914 tech tips 700 book. Can someone please tell me which is correct? I need to make sure the timing and valves are adjusted properly.

QUOTE(Jack Standz @ Jan 15 2026, 02:04 PM)  Photo thats a D Jet fan - its different to the L jet 1.8 @mcericmc - the timing mark on the 1.8 fan is the 7.5 before TDC. its the only mark if its an orig fan. i think pelican parts may have confused their info with the D jet engines. which do have a TDC mark on the fan (as well as several others). |

Thanks. I think your right. What REALLY confused me is the photo Pelican Parts put on the internet of the template inside the hole showing the mark in the notch on the fan to be TDC.
From everything I've read, the mark on the fan should actually be at the arrow on the template at 7.5 degrees BTDC. Once I got that figured out, I was able to use the template to put a mark for TDC a little more than 1/2 inch to the right. That picture really had me pulling my hair out.
