I would tune the generator around bit just in case osc is off frequency a good bit. If you don't get anywhere doing that would check the oscillator to see if it is oscillating. This can be achieved be listening for it in another receiver @ 260kc above the dial setting on victim. Or you can poke around the plate circuit of the 36 w/your scope to see osc activity. May need a low capacitance probe so doesn't load the circuit. Or use your counter to is if it's working and what frequency is working @.
If the osc isn't working it's time to revisit the osc coil. I think you said you rewound the tickler. Two important notes that will cause the osc to fail. If the wound in the opposite direction. Simple fix just flip the coil connection. The other is if there isn't enough turns. Best recollection is that  it's abt 15 turns or so.
