Subject: Re: [MBZ] '72 250/8 Carb Removal

Hi Michael,
You're in luck... I just did this last weekend! The trick is to remove the
valve cover. Then you can access the two inside bolts per carb with a
short 12mm open ended wrench. The out side ones are not bad to access...
you might have to remove a few odds and ends, but not much. My car is a
w108, but nearly the same setup as yours.
Last weekend I pulled off the carbs, then the exhaust, and finally the
manifolds. Today I'll replace the starter, start rebuilding the head
risers in the manifolds and reseal one of the carbs. Hopefully my new
parts (including a stainless exhuast) will arrive for assembly next
weekend.
Let me know if you have any questions along the way... I've done alot of
work with these carbs. You might find this manual I scanned helpful as
well:

Good luck!

Jaime-
Okay, went back out to go to work, and have discovered that I have yet
another problem. I DID take off the valve cover, and this did allow me to
get the carbs off pretty easily (well, only took one off for right
now-leaving one on so I can have it as a reference piece when reinstalling
the other!).
However, something I had discovered when trying to take the top off the carb
even while it sat on the engine (first plan of attack was to try to
disassemble it from the top down while still mounted) is that my carbs do
not have a screw holding them down under the air cleaner mounting pillar.
The manual I got says there should be screw there, countersunk under the air
cleaner mounting pillar/bolt. On mine the surface underneath that bolt is
very smooth, and does not appear tp be a screw that has been burred off, or
rounded off, but simply a solid surface with no slot, phillips indentation,
nor heax head hole or anything. Both carbs look like this. Was this a
modification done in the last year of the Zenith's used like this (according
to your manual)? There were a couple things where it says, "Up until '72."
Sound right to you? I only ask because the top of the carb still does NOT
want to come off. It says in the manual that you will need to pry it off
with a couple of screwdrivers, but I am trying and prying and it still
doesn't seem to want to let loos. And, of course, I don't want to be
bending things up on the carbs!!!
Let me know if this sounds familiar or makes any sense to you.
Thanks!
