never had that issue of breaking the carb base or busting off carb mounting fasteners , those are 5/16 threads , takes a lot to break them off , way more then should be applied to card hold down fasteners .
Are you referring to my post about replacing those bolts with studs and nuts?
If so I am referring to the fact that he's running the bolts in and out of that Aluminum Intake over and over and over and over and over again well guess what? Eventually he would strip the threads out. But if you're not referring to me disregard what I said although that is my reasoning behind me telling him he should get studs and nuts.
As for broken base plates I have bought carburetors with the corner broken off at the base plate. I personally have never broken one. Most of it comes from the guy tightening down two or three of the bolts without the carburetor sitting flush. Next thing you know he's got a broken ear on the corner.
