Timing confusion Options

[914itis]

Ok, either I am dumb, confused or a combination of both.

I am having some other issued with my car and decided to recomfirm timing once again. I went back to the pelican web site to make sure i got it right, then run into this. I was able to fing my timing mark on the impeller. I first followed the main instructions with thr first picture, showing how to to mark the 27 btdc



Then at the end there is a post by the much respectable Dave, showing an impeller with both the tdc and 27drgree btdc. (see pic #2)



the blue arrow shows factory tdc, red shows factory 27btdc, according to the instructions and template, should'nt 27btdc on the brown arrow?

Double-check the fan against the flywheel mark. I would trust the flywheel over the fan. But it might be prudent to check both against the actual TDC position. A chopstick should be OK if you have a 2.0 engine, but not a 1.7 or a 1.8. (Long story, don't ask!) A drinking straw might work for the smaller engines.
