Peter, have you checked for vacuum leaks? There are about 8 little rubber
fittings that dry out and may leak. If your plastic vacuum hoses seem a loose
fit in these fittings, it may be time to replace them. It may explain why
your engine didnt run so great at 4 deg ATDC since the vacuum retard is
connected for this setting. Verify your static timing for 10 deg BTDC.
Vacuum leaks can cause irregular idle.

Now, I should know better than to ask this, but...is it REASONABLE to
expect that the problem lies with the only 2 things I've messed with
(mixture and idle), considering it was running OK before I trashed my
adjustable needles? Just trying to be optimistic, and also avoid a hefty
mechanics bill...
