I did not, it was not that badly stuck and with a cleaning of Tri Tet
and re oiling it was nice and smooth

just did the AAR on my 73 cut slots with a razor saw bent them up . what
seemed to cause mine to stick open was a fine surface rust in the valves
bore. I tried to clean the oil gunk out which carb cleaner spray did. The
valve is stainless the valve bore is steel . I think it's the moisture
which all air has no matter oil bath or paper filter . The moisture causes
fine surface rust to form in the bore and scores it then this gives
something for the oil gunk to cling to rather than pass by. I polished the
valve and bore and then the valve moved freely. The only thing I didn't
think to do was lube the valve. I wasn't sure if I should use a light
coating of engine oil or thin grease. I can always place some oil on the
valve even after I crimped it back together maybe SAE 40 so it does not
leak down into the heating coil then just apply power to cycle the valve to
allow the oil to lightly coat the bore just to prevent rust. I have not
idea when made it they lubed the valve. The rust seems to take decades to
develop . It's a fine rust yet abrasive enough to slightly score the bore
and the valve. If I need to open it again I will not recrimp yet use small
machine screws and perhaps a thin gasket . The most difficult part was
getting the air filter end pipe back in place since it needs to be removed
the clean the valve and bore.

 Keith did you remove the valve?
