What’s up everybody! Was hoping to get this top end back together but of course problems…

I’m trying to put the cam and timing chain back on my 400ex. Trying to turn the flywheel over to the "T" mark to get the piston at TDC. Well, I can only crank it so far counter clockwise until there are two little single vertical notches about an inch apart but from my understating I should be able to freely turn it counter clockwise correct? I’m not going to lie i did try going the opposite way until I could go only so far and still didn’t find "T". Please Any suggestions?

I’m might add this is all new to me! Hope I’m not in over my head lol. I was to get it back together today.

Thanks ahead of time!
