Hey all,
I am new to this site and forum... I have a '48 D24 with a Sisson auto choke, recently while trying to troubleshoot rough idle and running issues. I found that the 2 bolts that hold down the automatic choke had broken off. I have read about drilling a re-tapping the studs, but what I don't know is if the studs thread into the exhaust manifold or if they were braised or welded on originally. From what I can see the bolts broke off flush and I cannot tell see if there are any marks from where they were to begin with. Really just stuck trying to figure out how best to repair this so I can get my D24 back on the road, a y help would be great.
