I'll post the photo again and add some words.

The objective here is to check or get the I-shaft gear properly set without need to go to the trouble of pulling the crank pulley to remove the bottom cover. You won't need a camera, or your wife's compact, but more importantly, you won't need your torque wrench and means to hold the motor.

If you noticed, your new belt had alignment stripes on it, denoting the placement of each index mark. The double-bar aligns at the crank. The single-bar marks align at the cam and I-shaft. Those marks are for installing the belt; they don't line up again for a long time* once you turn things. Take a look at your old belt, the marks may still be visible.

Yes, the I-shaft has a corresponding mark on the timing cover you can see here: -link removed-

But, it is hidden with the bottom cover in place. The timing is set by the number of teeth in the belt. That's why a timing belt has teeth. If you look at the installation stripes on the belt, you see they are a given number of teeth apart. That number is 44, counted between cam and I-shaft. You merely need to back the crank up a few teeth so the I-shaft mark is exposed, and then you can count the teeth between index marks, even though the white marks no longer line up.



After getting the I-shaft set, you'll need to re-visit the distributor timing, allowing for the possibility the last guy in there gave you the challenge. The end result should have the ignition timing set correctly at nearly the center of the adjustment range for the hold down bolt.



This isn't your distributor, but the mark is what I'm used to seeing.

Some mistakes are too much fun to only make once.
