Is that little throttle travel from wear in the whole linkage setup or poor design? Or a mixture of both. I've had to educate myself on what a 2+2 E type was 😳 Tom mixture of everything over 50 years of use. I also strongly suspect that the carb butterlfly's didn't open fully from the factory, possibly to ensure that if the car was spot checked in america it met emissions. |

Is it worth replacing it with a cable & sleeve? i read that mangoletsi do a cable throttle kit, but i won't investigate that until i'm ready to do the RHD conversion. the LHD cars have a floor hinged pedal and the RHD cars have top/bulkhead hinged pedal so theres options to look into (depending on fitment/price/availability etc). |

After looking at pictures I personally think the 2+2 is better looking. Its longer and looks lower and sleeker because of it. |

It gets better....they fitted a dizzy with vacuum retard for Uber lean running.....yes retard rather than advance. Plus burp valves and temperature compensators on fixed jet strombergs mean power was down by 25-30bhp approx compared to the series 1's. I have a 123 Bluetooth tunable distributor going in plus a Bosch blue coil which should recover a lot of power , alongside an adjustable needle conversion for the carbs. |

Oooh this is brilliant. Can we see more? I love that unrestored patina.

Wide Open Throttle
you'd be surprised how many cars don't get full throttle

Thought this would be a relatively simple job but turned into a session, replacing that hard bush. the bush hold the rod that goes from the bulkhead throttle linkage directly to the carbs. the bush was rattling around allowing a fair amount of play in that rod. Pulling the bush out showed that the original factory bush had disintegrated and the rod had been mashing around for a few years, ovaling the bracket hole. A new bush had gone in ages ago but was worn out too. . Trick is to fit a oilite bush but needed a bit of weld to rebuild the circular hole to locate the bush correctly. Then a bit of paint, then a wrestle to get the buqqer back in as the carb rod had detached right under the manifold.Then a final adjustment of the whole linkage again.    |

My thoughts exactly. Nice to see things being done right! Did you drive the car before starting work on it, have some comparison? |

Whilst that does indeed look very neat, given that this end of the linkage is mounted on the bulkhead, doesn't it need some 'give' to allow for engine alignment & also movement, hence the original type of bush? My Amazon has a similar set up, and pretty certain that it uses rubber / nylon there. Or is there enough length in the rod to allow for that?

Nylon was most likely used for ease of assembly and cost.

You'll see the significant gap on the rod stop to allow for movement forward and backward. What you can't see is the other end of the rod which allows for movement where it joins the main carb linkage.

You are certainly doing the right thing restoring the original linkages, the majority of the reproduction parts are appallingly low quality.

Will all of the smog equipment be going in the bin? I've blocked off the burp valves and the temperature compensators on each carb. Both of these are basically controlled air leaks for emissions management. I've also done the "crespin mod" which disconnects the secondary butterflies and wedges them open permanently. This gives about 80% of removing the butterflies completely but the manifold has to come off for that. Down the line, the carbs are coming off to make them adjustable. I'll then do the complete secondary butterfly removal along with the brass tube mod to block off the secondary airways in the manifold. Before all that, lots of other things to do first. |

Each carb has a burp valve (silver pointy thing) and a temp compensator (long tubey thing). I made a solid gasket for the burp valves which basically blocks the valve off. It's job is to inject air into the mixture when the throttle is snapped shut, leaning out the mixture for better burn and for emissions. But they gum up and stick open causing weak mixtures. The temp compensator is just a bimetallic strip that opens a valve as it heats up bleeding air into the mixture flow. Again, they go out of whack or the valves gum open causing havoc with the mixture. You lock the valves closed by clamping the bimetallic strip tight but I wasn't convinced it held the valve fully closed so added a strip of steel over the bimetallic strip to lock it shut.    |

Sounds like the exhaust/manifold has seen better days Exhaust is proper redneck job, just like the falcon sprint I imported. Fully welded front to back. Both rear resonators are holed. Both front downpipes are split and the middle boxes are slim cherry bombs things. Probably no baffling at all. Sounds like a tank starting up. Complete new system is here ready to go on. Photos to follow. In other news, the DVLA have issued the logbook UBD767G. 4 week turnaround |
