I am looking for a source for a replacement plug that goes in the airhorn over the lean stop adjusting screw for the mixture control solenoid. A previous rebuilder left the plug out as its commonly suggested to leave it out for easier readjustments. However, one of the purposes of this plug is to lock the adjustment so the lean stop can't migrate out of adjustment which is an issue I am having. I detected that without the plug, my lean stop adjusting screw vibrates upward and limiting plunger travel, thus making the mixture rich and screwing up the dwell. Moreover, I am having an issues finding a source for replacement plugs, Quadrajetparts.com had them but they are currently shut down and who knows when or even if they will reopen. Anyone else know sources of oddball E4ME parts? Worse comes to worse I can try extracting a used plug out of one of my spare parts Qjets.
One more note is that my current carb has a old lean stop repair kit installed. This repair kit replaces a stripped out adjusting screw with a special stud and nut. It seems stronger but looser than a stock screw, the nut turns easier than the stock adjusting screw so it might migrate worse than a stock screw and has a greater need for locking.
