Carb Studs or Carb Bolts?
Mounting studs or bolts should never stretch on a carb as your only torquing them down 7-10 ft lbs, like finger tight and 1/4 turn. But as any bolt into AL, Id stud it (with anti seize) just to prevent the wear on the AL threads. Bolts as said require you to insert the bolts under the accelerator pump linkage and other obstacles and then lower carb onto intake while threading them. PITA when a stud is just sneak a nut under there and tighten.
