Poor results with IF alignment can be due to overcoupling the input. Just a half turn of wire taped around the mixer tube gives adequate injection with minimal circuit loading. Then attenuate the genny down to the level that still gives a stable trace on the scope. And you should be good to go.
The 415 is an excellent instrument (or was back in the day).
