That's what the tuning slugs are for and the complicated instructions. If the tuning cap goes to the ends and it doesn't pick up the full band, the slugs need to be adjusted in a certain way, with a sig-gen, o-scope, VTVM, and a bunch of tuning tools. Sounds like the low end is ok, but the top end is off a little. spend the $$$ for an alignment and get it done right. Well worth it.
