While going over the Simms injection pump on this old girl,(1958 Dexta) I found that the Pneumatic Governor Air Filter Capsule (whatever that is) has been replaced by a wad of very tighly packed heavy-weight steel wool.
Now I'm sure that there is supposed to be something there that will act as an air filter for the governor, but I'm also equally sure that this wad of crap wasn't filtering anything, or for that matter allowing any kind of air into the governor.
Now, my questiion is, just what is supposed to be there?
I've tried to find out from local fuel injection pump service people but to no avail.
Help is appreciated, advise is considered, good advice is golden.
