Tim,
If you have a local LBC parts place you might go down there and ask if they have
a box of carb gasket spares they might have saved. Jim from Kats British Car
Service(303-730-0877) here in Denver saves all the spares and he was kind enough
to let me go through them to find the right by-pass valve gaskets for my carbs
(the ones that came with the kit leaked like crazy). He might even find you one
for the starter box cover if he's not too busy and you fax him a picture of it.
Question for the list:
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
front carbs have a non-adjustable choke stop.
Thanks
Bud

Subject: TR6 Stromberg carb question

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.
