I need to make sure the OPDA is aligned correctly, as this may be causing some of the engine issues I am having. Best way I've heard is to find Top Dead Center, and then line up the alignment pin in the OPDA. What is the best way to find TDC? I've read a bunch of things online but none of them are very clear. Figured I'd ask the experts here

- Pull the spark plugs out
- Stick your finger in the No.1 spark plug hole and rotate crank until you fell the air rushing past your finger. As soon as you fell the air stop rotating the crank. Then carefully rotate the crank until the little notch in the back of the crank pulley lines up with the 0 on the timing marks. It is just in front of the end of the screw driver and has a yellow arrow pointing to it. Might take a few rotations to get the feel of which is the compression stroke verses the exhaust one
