Removing spark advancer

[80hondaf]

Looking for some help, I need to remove the spark advancer on my 1980 CB750F and was wondering if it is a left hand thread or is it just being really stubborn, I've wrenched on it pretty hard and it's not budging.

Right hand normal thread but they loctited some of them and a b-tch to get off.
