Stromberg Throttle Cable

[RogerFrench]

I have acquired a UK-style inlet manifold, and although I'm pretty sure I can make a bracket to hold the throttle cable outer, it would be nice to see how Lotus did it. Similarly, how were choke cables arranged for both carbs, please?

Any photos would be excellent, or if you could point me in the right direction to some I've missed, please

That will be of interest to me as well, the airbox has been removed from mine and from memory the throttle cable bracket is a lash up and the choke has no means of connection.

if no-one replies I could take a trip to photo my throttle set up but I am pretty sure thats its a PO lash up.

Here's a picture of my Stromberg set up. The throttle cable arrangement is, to the best of my knowledge, Lotus's version (mainly - don't look too closely at the far bracket bolt!). The choke cable should be one continuous loop that goes through both carbs but I found that to be really heavy so I changed it to two separate independent cables.

Thanks Stuart. Unfortunately my cambox cover doesn't have the threaded bosses like yours. Oh well!

How do you operate the two choke cables? Do you have a 2-into-1 join somewhere out of sight?

Here's a left hand drive version, there probably are others; don't know if it's Lotus-original or not.

Throttle cable attaches to a fitting coupled between the two carb throttle shafts; choke cable attaches at the fwd carb only. First pic is a global view, second is a close up. Sorry for the blurry image; if you need a better one, let me know and I'll have the wife do it right.

Ok, the wife saw my blurry pic and wouldn't let that stand.

Here's her pic and I have to admit it is better. I wish I knew how to make it larger for easier viewing

Roger, I have 2 camcovers with the threaded platform for the stromberg cable. I;m willing to swap for one without. One of my twincams has webers and the other Strombergs. I'm in California if you willing to pay shipping for both, im willing to swap one. Neither cam covers have any issues.

Thank you all.
James, I have the ribbed Big Valve cam cover so no swaps, sorry!

For the choke cable there is an easy conversion to the split cable used by TR6s (Triumphs). Carlos

Here there are some pics.

One of mine is from a US model oxymoron Stromberg Sprint (ribbed) but no worries. I like the old style better, with LOTUS on the cam cover portions.

No 2 into 1's or anything like that. The original cable goes to the rear carb and I added a second cable for the front carb low down on the bottom right of the dash (rhd in UK remember!). The dash isn't the car's finest point so I wasn't that worried about drilling holes. I've set the fast idle cams differently on the chokes so the rear one does richer and faster but the front one richer only. It helps as the car warms up as I can juggle the idle speed vs richer mixture as the seasons change.
