What is Top Dead Center on the crank if your trying to set back your timing to stock. There's two markings on the crank a red marking and white marking.
Which one do you line the notch to when trying to set the timing, the white or red marking.

 

i think it's the white marking. i never figured out what the red one was for.

 

red is for BTDC timing adjustments

 

red is 16 degrees BTDC, and the two adjacent marks are +/-2 degrees.
