broken stud

[p24-1953]

i snaped one of the studs holding the sision choke down, is it okay to secure it with just one side, or will this cause a grounding problem? how should i remove the broken half with out damaging the intake?

is it broken flush or proud? regardless of your approich to try to reverse bit drill, drill and tap...I would suggest a few heat cycles of the broken section and application of candle wax to detroy the rust bond and promote a lubricated effect to the threads prior to either methods you should choose to attempt...

Boy, with all the heating and cooling over the years, those choke bolts sure get fragile. If it will hold down tight with one bolt I wouldn't think grounding would be an issue. You can try to drill out the old bolt and replace it. At least it's pretty accessible. Plenty of older threads about broken bolts and studs and how to get them out. Have fun!

Since its mounted on the exhaust manifold, why not just drill it out and tap a new threads in the hole. Replace the old bolt with a new 1/4-20 screw and you're done. Shavings will go out the tailpipe.

What about metal shavings dropping down into the intake manifold getting sucked into the combustion chambers ? Not to worry ? Perhaps pull the carborator and hook up a flexable hose to your vacuum cleaner to get the debris ? edit ; The fist post states intake manifold but I guess that it is the exhaust manifold , so no problem there .
