Enya 53 FS

OK here is one I have not seen before and would like some halp on.
I have a NIB Enya 53 FS and I went to bench run it last Sunday. during the first and subsequent two runups I noticed raw fuel leaking out around the cylinder head bolts and possible the glow plug, it's hard to tell.
My first clue was that this little Enya sucked back 12 oz of fuel in about 4 minuetes! Now I know youare supposed to run an engine rich for the greakin period but this fuel consumption seems excessive. I stopped the engine, let it cool down then checked to make sure the bolts and glow plug were tight and they were.
So now I don't know what, if any, problem there is with this engiine.

Are you sure the excess fuel is not coming out of the front behind the prop washer and just blowing over the crankcase?
A front intake running excessively rich will sometimes blow fuel out of the venturi.
Forget the "Run it rich" nonsense. Use a smaller prop than normal and run it at its normal rpm on the rich side of peak.

I have seen new engines where the low-end adjustment is so rich from the factory, that fuel slobbers out the carb.
Are you sure it's not coming out of the carb?
