First: how on earth did you get your nib out of there?! I've got a VHS steel age (actually mine is the 25th anniversary edition) and while the nib/feed assembly unscrews from the body easily enough, I've never gotten the collar off.
Second: earlier today - just MINUTES ago, in fact - I received my pen back from Dan Smith, e.g. Dan @ FP Geeks. I was logging on to the forums to write effusive praise for his work. Keep an eye out for a longer post about this, but suffice it to say he took a pen that made me want to rip my hair out and sent back a writing instrument that FINALLY makes me go "ohhhhhh ok, NOW I get what all the fuss is about."
Among other work, he corrected the PRECISE problem you're showing here - way too wide of a gap between the tines. The pen still writes nice and wet but is no longer firing ink uncontrollably onto the page.
So, +1 to those who have said "send it to an expert," and a +++++++++ for Dan's work on these very pens (firstname.lastname@example.org)
edit: forgot to specify that the pen in question was in fact my Visconti Homo Sapiens. Which was the whole point but I neglected to be specific. D'oh.
