Post-War Other Herald carpets and throttle issues

[TomMull]

I posted on another thread that I would comment on the new carpets I'd ordered from Newton's and since I's been a while I thought I'd begin anew.
Really nothing extraordinary about the very nice quality carpets, I'm generally pleased but quite pricey. Might be good to wait for a sale from Moss or one of the others although I haven't seen their carpets so can't really compare. PM with questions.
Since I had removed the gas pedal with the installation, I decided to replace the jury rigged Spitfire accelerator cable that I had installed last year with the proper one from Rimmer Brothers. What I didn't count on was that it appears as though the part number is correct, the hardware on the carbs may not be. The cable does not match the terminal sleeve on the carbs and the angle is off even if it did fit. In short it is stickier than ever.
Here is a picture I found on line. I don't know if if this is the correct setup but it sure looks better than mine. I was unable to find that bracket setup on line. I could fabricate something but it would be awfully nice to just buy the correct setup.


Here is mine:


Finally, the pedal termination seems to just drop down from the top of the firewall with no support anywhere near the pedal, Does that seem right?

Well, the one thing I can confirm is that your last picture -- pedal termination of accelerator cable -- seems about right, based on my Heralds.

Now, here's the deal: Do you still have the original cable, the one you replaced with the "jury rigged Spitfire cable"? If so, how did it differ from what you have now? Thing is, there's pretty much no exact documentation that I'm aware of for how the dual-carb setup was "supposed" to be on the Herald 13/60. Why? Because the only Herald 13/60 models that ever came with anything but a single Stromberg were those several hundred built in Belgium for the Puerto Rican market and, therefore, using dual-carb SU emission-tuned Spitfire Mk3 engines to meet Federal standards! (Of course, the Spitfires of that era used a ball-jointed linkage rather than a cable.) Unfortunately, I didn't take anywhere near enough close-up photographs when I last saw this car 17 years ago, so I can't vouch for some of those little original details.

I'm wondering if the early Spitfire MkIV "rest of the world" specification might be of some use here. The MkIV had gone to cable operation of the accelerator, and markets other than North America retained the dual HS2 SU carbs. Parts for such might still be available from the UK vendors? I don't know, and I don't really have much information handy on how that setup worked; only what I can see on vendor sites...and I'm not having much luck finding what I'm looking for. You might surf around the Canley Classics site; maybe I'm just too tired tonight to spot it.

I did find this page on the MkIV carburetors; maybe it will help?

Thanks for the reply, Andy. I usually don't throw anything away, but I can't seem to find the old cable. I'll look around more thoroughly. One thing I do remember is that it did fit the termination sleeve on the manifold bracket (the threaded thing you adjust the length with), but the angles were quite wrong, and it did not operate smoothly. The Spitfire cable I used to replace it seemed identical except for the length and that it terminated inside just under the firewall, instead of at the pedal.
The cable I got from Rimmer would have worked better, I think, if it had fit the sleeve at the carbs. As a matter of fact, it looks to me like that would have been the original setup, poor angles and all.
I guess what I'll do is make a bracket to correct the angles and use a modified Spit cable. All it takes is an additional link between the firewall termination and the pedal; simple enough.

Tom, does the manifold still have what looks to be an almost "triangular" piece into which the end of the accelerator cable sheathing goes? See this picture from 1999 (again, I wish I'd taken more and better close-up detail shots)?

 

[TomMull]

Yes, Andy. Exactly the same, including the 60 degree kink just as the cable housing goes into that point. Tom
