Hybrid studs for an application like this seems odd.Sounds like the carb has 1/4-20 threaded holes, so using 1/4-20 studs seem to makesense.I did a little internet search, and found this link to a Continental parts manual:http://rob.com/matt/manuals/O-200_Parts_manual.pdfOn pages 28 and 29, the relevant components are shown (scan attached), and thestuds (index no. 28 ) are identified as "Stud, Plain, 1/4 x 7/8 Inch long". Theassociated 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 knowswhy. I can't see why it wouldn't be fine to just use 1/4-20 studs, and sometype of locking nut.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ttachments: http://forums.matronics.com//files/c85_ ... __________

I think the question is why was course threadused on the engine side? Is it, as I suspect,that course threads are stronger in the softcase material? I'll bet that having fine thread on the other endisn't so av nuts could be used but that aviationnuts would go nuts trying to figure out whysome acorn would throw a brazil in the works!ClifAs we acquire more knowledge, thingsdo not become more comprehensible,but more mysterious.
