I'm trying to adjust timing on my 2.0L and ran into an issue. The bolt you loosen, to rotate the dizzy, is underneath the vacuum can. I can't seem to find a tool to get under there to loosen or tighten. I've had the dizzy out and removed the vacuum advance and it's no problem getting to it. Is there something way off with my distributor?
Thanks for telling me the secret.

Post a picture from above.
Close enough to see the whole distributor from above
Far enough back to see the nearby fan housing.

You may have the vacuum can on backwards, but not sure how you could.

The nut to loosen is 13mm, and using a wrench you can reach it.
