Stop in for a cup of coffee

So the mechanical timing looks like this:
14* initial at 800 rpm
14* at 1400
32 at 2500

Without vacuum advance, that should be OK. It could be tweaked but that should be close enough to be workable.
As Dave mentioned, decreasing timing can put more heat into the engine. Nothing wrong with 190*. In fact arguably that's better.

I'm with Dave. Its prob carb tuning time. Isolate the conditions if possible.
