Double layer primary

all,

I test my coil a few hours ago and encountered a problem. the coil
worked well and performance nearly doubled, even without tuning, but
tuning is very difficult due to the proximity of the layers of the
primary. Is it OK to just leave one tap on the bottem layer on and
just adjust the top tap, or is it necessary to move them so that they
are equidistant to the ends of the tubing? Any help would be much
appreciated.

Cheers,
Blake
