I have a 16.5 hp Briggs Twin (401707 0111 04) on a B165 Wheel Horse. I snapped the bolt that holds the points cover on (#12-24 x ???). I think someone used Red Loctite on it. Now I need to drill & tap it, but how deep can I go? Also, is the hole square with the front of the engine or does it go in on an upward or downward angle?
Alternatively, how long is the bolt (minus the head) (Briggs 93854)?
