a late reply, but it certainly is a summer/winterposition for the choke
I found an illustration in a mid 70's technical book (time/life) in which
this is explained!

>If you have a local LBC parts place you might go down there and ask if they

enough

carbs

you one

it.

>Speaking of the starter box/choke. I was wondering what the "stop" is for
on
>the starter box cover/choke. It's hard to describe but it's a spring
loaded
>(brass looking) pin with a knurled knob on one end and a slot for a
screwdriver
>on the end of that knob. The pin goes through a hole in the starter box
cover
>and sticks out. Where it sticks out there is a hole in the pin with a tiny
split
>pin that fits into the hole and extends out each side of the pin. This
split
>pin has two positions it sits in when the brass pin is pushed in on it's
spring
>and rotated 90 degrees. The end of the brass pin acts as a "stop" for the
choke
>cam lever and it can be set in two positions. The two positions function
to
>"stop" the choke cam lever (in either a more choke or less choke mode) when
the
>choke is pulled out to it's full-choke position. The difference in the two
>positions being only about 3/8 inch.

>I've seen pictures of them in the manuals, ZS (the cover), Haynes (p.65),
but
>nobody ever puts a name to the pins. Bentley had one picture (p. 24 Figure
63)
>with the pin numbered (5) and an arrow pointing to it, but then never
refers to
>the number in the text.

>Now if you can figure out what I'm talking about from that....can you tell
me
>why there are two different stop positions for the choke when it's in the
>full-choke position? In other words....why is the choke stop adjustable?
It
>also appears that only the back carbs have this adjustable choke stop while
the

>I just finished dismantling and cleaning the two Strombergs on my 1974
>TR6 purchased in October. The PO gave me one carb kit (in a plastic
>bag) and I bought another, but the PO's kit did not have a gasket for
>the starter box/choke assembly which the other kit had. Neither carb
>had the gasket when I took them apart. One of my catalogs shows the
>gasket but does not have a part number for it, and another one doesn't show
>it at all. I decided to leave them off. I cranked up the engine for the
>first time a couple of hours ago, and it caught right up and sounded
>pretty smooth with no adjustments yet, but the forward carb is leaking
>gas and it appears to be from the starter box. So it seems that the
>gasket might really be necessary even though it wasn't there before
>and there was no leaking before. Do any of you out there remember
>whether your manual choke Strombergs have the gasket? And is there a
>way to buy another one without getting the whole rebuild kit?

>Thanks for any help.
