| Rob,
Does the stuff in the bowl have a fine texture and brown in color?
I've had problems with all my carb equipped cars with this type of
gunk in the bowls. It seems to be much more prevalant during the
winters months with the oxygenated fuel they use in the Northeast.
Something in the additives appears to be what's getting left behind.
As far as the type of filter you are using. I run the same type as you
on my '67 Firebird and my '71 Monte Carlo (had a Carter AFB, changed to
a Holley 3837 for performance reasons) and have never had a problem. In
fact my '85 K10 and '84 Z28 had more problems with the factory style
filter in the Quadrajets letting more crud by.

Chris,
Yeah, the bowls both had the crud, which was as you described.
But when I pulled the left bowl, cripes, there was a damn tree in
there! The offending item looked to be a piece of grass or a sliver
of wood, although I didn't taste it to see if it was minty like a
toothpick.
Around here in COS we have oxegenated fuels in the winter, that's the
probable cause of the gunk in the bowls. So I'll run some cleaner
through it once in awhile.
So, you like the Holley better huh? The reason I picked up the AFB
was 'cause I liked the way I can practically rebuild it _on the car_,
and it's simplistic design. Do you think the secondaries are of a
good design? Sometimes it appears they should be opening sooner.
Thanks man!

| I put the Holley on 'cuz I got it cheap, $35 for a 3837 ('67 396 350hp)
that the previous owner had purchased new and when bolting it on he
snapped the base. He had it sitting in his garage for years before I
bought it. Found someone to weld the aluminum base back together for $25
and walla, a never used '67 Holley.
I really never had any problems with the Carter AFB that necessitated
me removing it. I had purchased a street/strip jet/needle/metering rod
kit so I set it up to perform well. Tom Fisher (those who have been around
awhile will remember him) has a 300hp 350 GM crate motor with the
Edelbrock AFB clone that he's worked wonders with. He spent weeks
tweeking the jets and metering rods until he got the performance he was
looking for. Yes, his carb ended up with crud in it too.
I think he ran a best of 14.8 (Bruce Augenstein may be able to correct
me on this) at something like 98+ in his 3:23 geared, 4spd '81 Malibu
Wagon. Traction and gearing was his limiting factor. The engine, with
the tuned carb was pulling hard.
