    Richard,

    Did any UK cars have the bypass valves or were they just federal?

      Terry i don't think UK cars had bypass valves. I bought two sets of carbs out of uk for my Fed. no bypass. I needed the ports for vacuum advance. found out that British vacuum can add that port

            I don't think so, Stag was a very long time out of production before Englandshire got anywhere near Californian levels of emission control

              OK

              Yes, all the Stromberg carbs from 71 on seem to have them here, no matter what car, maybe in Australia later on as well.. I’ll keep that in mind before I jump in next time! I adjusted them 2 turns out yesterday and yet to test, the MGB needs some loving.

              My stainless exhaust looks stock but is pretty loud, I’m sure that’s the main reason for my popping, no major leaks(I did a test with the blow of a vacuum and soapy water) and I have a wide band O2 so know the mixture is fine.. all I have to do is crack that throttle and it quiets down.. the quest continues!

                  No problem..

                  Its an innovate LC2 sensor driver with Bosch O2 sensor. You can buy them without any gauge and use the free software they have to give a gauge on a laptop or suchlike, I’m not bothered about watching it in normal driving, just when I’m tuning so just hook the laptop up then. The advantage is that the “gauge” is as big as the laptop screen so easily read. I mounted the device on top of the relay board and ran the laptop cable into the glovebox.

                  It comes with a sensor plug which I welded into the left down pipe around the starter area. From either side you can read both carbs anyway. I set the needles exactly the same and then adjust them equally to get a good reading, I usually go for around 13.5 -14 AFR, slightly rich of stoichiometric at idle. After a few drives I check the plugs on each carb (2 and 4 are convenient) to make sure they look the same, if not tweak one and reset the AFR

                    Thanks Terry, did a quick search - is this the unit? Bit pricey!, are there alternatives for cheaper sensors and laptop s/w do you know? https://www.demon-tweeks.com/uk/inno...oller-2005080/

                      About $50 more than in USA..

                      I have always (well both times!) used the innovate one.. it’s generally the best value available for a wide band.. maybe shop around a bit?

                            Terry, looks like it uses a serial port connector. If so, is this compatible with a USB-Serial converter or do I need to hang onto an old laptop?

                              I have been looking at these, thought it just need to put a boss on each of my cars and I can then move the kit form car to car to "set them up" then remove and screw in a blanking plug. Anyway, according to the instruction manual:

                              "Connect the OUT port of the LC-2 to the provided serial programming cable. Connect the other end of the serial programming cable to your computer. If your computer does not have a serial port, you can purchase a USB to Serial adapter from Innovate Motorsports (P/N 3733) or use any USB to serial adaptor that includes drivers."

                              https://www.innovatemotorsports.com/...C-2_Manual.pdf


                              The going rate in the UK for the complete kit including Bosch sensor (the most commonly used one) seems to be in the 160 to 180 region. From the USA it is around 140 but with 40 shipping plus customs duty!!

                              So many cars, so little time!

                                I have a usb/serial adaptor cable, works fine.
