67B loading up

[Carl French <cfrench@cybertours.com>]

I have a 67 B freshly rebuilt 5 main with HS4's (rebushed). One of
Lawrie's sport cams (timed only to the two dots lining up). original air
cleaners, mech vac advance not re hooked up (did so late last night).
New NGK plugs, new points, Has a problem of loading up while idling at
lights and in traffic, showed itself in Conn two weeks ago and getting
worse ever since. Confused by the 'getting worse part' any ideas of the
group?
