Sounds like the carb has 1/4-20 threaded holes, so using 1/4-20 studs seem to make sense. I did a little internet search, and found this link to a Continental parts manual: http://rob.com/matt/manuals/O-200_Parts_manual.pdf On pages 28 and 29, the relevant components are shown (scan attached), and the studs (index no. 28 ) are identified as "Stud, Plain, 1/4 x 7/8 Inch long". The associated nut (index no. 29 ) is identified as "Nut, Plain, Hex 1/4-28. So, based on this info, the hybrid studs probably are what was used. But who knows why. I can't see why it wouldn't be fine to just use 1/4-20 studs, and some type of locking nut. Bill C.

Is it, as I suspect, that course threads are stronger in the soft case material? I'll bet that having fine thread on the other end isn't so av nuts could be used but that aviation nuts would go nuts trying to figure out why some acorn would throw a brazil in the works!
