Todd is right. I just looked at my 110 (use same carb) and the manufacturer cast the carb BOLT mounting boses 90 degrees wrong. They should be at 2 o'clock and 8 o'clock, rather than 10 o'clock and 4 o'clock. Wonder how that got out?
I happened to find a pic of the corrected arrangement for comparison's sake.

What happened is you have one of the first BME 102's. The machine shop messed up the cases
They were fixed on the next run of cases.
