14.5 ohv briggs(adjusted valves, binding(?) before compression. Help!)

She was hard to start, adjusted the valves, ran ok, then same prob, take the plug out and she would turn over fine, although did seem to hesitate before tdc. Ran ok but was losing oil, traced it to carb from blowby(?) Any help would be appreciated.



Seems to point to cam shaft compression release, Ill tear it down this weekend. (Unless someone thinks it may be something else.)
