Hi Scott,
I'll have to be brutally honest that it really looks like chrome paint from this end. I will say though that I don't mind it at all, but it's definitely not the original colour as the Briggs & Stratton colour was more of a greyish / silver metallic.
It's your call though as it's your mower and your work. If you were intending for it to be a concourse faithful restoration then there are quite a few deviations you have already transgressed with, so then what difference does it really make if you changed the shade of the engine paint to actually be far more striking than it originally was. (as it was quite dull originally)
If you leave it as it is I feel it'll be one of the nicest and most striking 14 inch Scotty's we've seen on here and believe me we've seen quite a few 14 inch machines over the years.
Cheers,
BB.
