Just wondering if there is a tried and tested way to check base timing (all valves fully closed) without removing the valve cover? Any help would be appreciated!

you can try to take off the oil cap and look inside w/ a flashlight, but I don’t know if you’re get anything out of it.

I can’t really think of anything else without taking the cover off… it’s not a big anyway, why not just take it off?

hey guess what, the time it took you to post this the valve cover would have been off.
