I feel like that one's about 1.5 turns out on both screws but I might be a little off. Somebody will be along to confirm or deny soon.....

ok great just cleaned them there a re at .013 but way better can see them arching when running and they have burn markes so I think im gonna clean them some more and reset gap and get a new set.

try really hard to spend some time cleaning the old ones. Unless they're badly pitted, don't replace them. Lots of us really prefer to keep the older ones if we can.

Sparking at the points can be caused by mismatched surfaces after filing.  Also, if there is pit on one side and buildup on the other, that indicates the condenser is not in spec.  A good condenser will greatly reduce sparking.
