broken bolt in exhaust manifold

[melhilburn]

Any advice on how to remove an old broken stud bolt from my 1964 292 exhaust manifold - One of the (2) that that the intake manifold bolts on to?

Also - If I do a good through rebuild on my rochester 1bbl carb is it just about as good as buying a new carb?

[melhilburn]

is it possible without removing the intake manifold first?

Best to remove the manifold. If there is anything still sticking out, weld a washer to the nub, then weld something to the washer that you can get a vise grip on. Let it cool, you should be able to screw the stud out. Might take more than one time. Letting it cool is critical along with good weld penetration on the stud, the stud expands with the heat, letting it cool should break the stud loose.

The carb should be soaked in carb cleaner to make sure all the passages are clean, blow out all passages with about 20psi air pressure. Best results are to have a pro re build the carb.

i usually take a nut that the inside is the same size as the broken stud hold it over the broken stud with plyers weld filling the inside of the nut to the stud while it is still hot turn it out i have not ever had this not work!!!!

and learn from my mistake of drilling it out to much and then having to retap the hole to a different thread
