alright, so....i went to embark on my first carburetor rebuild yesterday...
i have a 1966 mustang with a 200ci straight six, so it has the autolite 1100 carburetor. it came off fine, and i began taking it apart. everything seemed to be going smoothly, as i followed along with the diagrams and instructions.
then i came to a discrepency. on the exploded view and diagram of my carb, it showed the 1100 as having the "valve vent rod" and "vent actuating lever" steming off the accelerating pump assembly...so basically the lever is on top of the carb.
but not on mine. i was puzzled, and when i looked it up online, all pics i found of the 1100 seemed to have the valve vent rod up top.
i didn't know what to do, so i kept going. mine does seem to have a rod inside the carb...i'm guessing this the valve vent rod??
please see attached pictures....






so i'm a little confused...

also, the more i read about the 1100, it made it sound as if the manual mustang carbs had only one diaphram, and the autos had 2, one on each side.
my car is a manuel, but it has a diaphram on each side...one for the accel pump and one for the dashpot. did i mis-read something??
thanks

I've seen rebuilt 1100's with the vent rod hole plugged off like yours. I don't know why they do this, sorry. I guess it's not a big deal to do. Yes, M/T carbs have 1 diaphragm & A/T carbs have 2 diaphragms.

You probably have a rebuilt carb that could
be a combination of different carbs. I have
seen them pluged off like that but most have
the venting rod.
Yes, that is correct, dual diaphram was used
on A/T cars and single diaphram was used on M/T cars.
I see that you have the SCV (spark control valve)
on the side which is correct for 65/67 cars.
If you are looking to get the correct carb for
your car leave me a PT (private topic), I may be
able to help you out.
