Will, the vinyl electrical tape you used between the coils might be part of your problem. Vinyl is very lossy at RF freqs and could cause enough loss to make the osc marginal.
A better choice might be teflon tape, sold in hardware stores to seal pipe threads. Teflon is very good at RF and has very low loss up into the GHz region.
Might be worth a try...
