  1. Charlie D,

    Yes I remember the truck stop on the A40, wasn't it red and white (perhaps). Yes I believe houses built without permission and ground to a halt for many a year though now occupied.

    I think the truck stop made a come back as "The Cotswold Outpost" just a few yards to the west of the houses.

    Didn't you ever exit the A417 at the Highwayman Pub and down the lanes to appear at either Birdlip or Ullenwood and avoid the Air Balloon roundabout?

    I was a daily user on the A417 for a couple of years.

    Wow,

    I had not heard of this until today, seems to be more of a Chinese type regulation than the UK. If this is the start of a draconian roll out over the rest of the country then I won't be a happy bunny.

  3. I have a PI. and have just come late  to this thread and have had a quick read through and have noticed that I could find no reference to the fuel tank,

    In a TR the fuel tank sits very high, remove the feed to the MU and fuel flows from the tank however much fuel is in it. At no stage can the MU leak back to the tank. Similarly the injectors are only a couple of inches below what would be the fuel level in a full tank  and could generate little back pressure to leak back to the MU and the tank. 

    Does you starting issue relate to the quantity of fuel in the tank?

    If you were feeling really keen a full tank and lifting the rear of the car six inches  would ensure the injectors and lines were below the level of fuel in the tank and could not leak back and any poor starting could not be attributed to the injectors draining back.

    There are two types of fuel pump a turbine pump or a gear pump. A turbine pump uses its rpm to generate the fuel pressure and usually operates at the 14 volts whilst running and when starting may have 10 volts are less and consequently spins slower. A gear pump  pushes the  fuel through meshed gears and is less prone to reduced pressure on low voltages. Once again if you were really keen you could disconnect the wiring  on the fuel cutout switch and temporarily connect a second battery to determine if low voltage whilst cranking is affecting your pump.

    In one of the posts above I saw connecting an airline to the injectors to check the  pressure at which they open. If you are going to try this then point the injector into a bucket with a  couple of inches of water in and with the injector 6"  above the surface observe the spray pattern on the water surface. I have had injectors the do not fully open and only produce a semicircle of spray, good enough for hot running but reduced atomisation when cold starting

    Because the TR has a low pressure injection system it does not atomise the fuel very well with a cold manifold particularly if the injecting - valve opening timing is not good and the fuel is not instantly drawn into the turbulent air entering the cylinder when a good fuel=air mix is not possible. Once the car is running the heat in the manifold masks the issue. It is normally combatted by the choke over richening the mixture inorder that than a larger volume of fuel can vaporise to a critical explosive mix.

    As in a previous post start the car and once running for a few seconds turn off and leave for a few days to eliminate any issues of heat soak into the injector lines and creating a vapour lock.

    Do you have any talcum powder? Liberal dusting around the metering unit fuel pump, pressure regulator and pipe  unions is the one of the best trackers for small fuel leaks that typically evaporate before they leave drip marks.

     

  4. George,

    Not sure what your looking for but I stayed one night in Ibis budget Mulhouse Centre Gare, pretty basic hotel but has underground car park with full security gate (not barriers)and cameras.

    Next morning I went off to Schlumpf museum on the local trams - really nice experience and cheap easy to navigate and the hotel let me leave the car in the car park FOC  untill I returned for it at about 3pm to head off for pastures new.

    Trams stop opposite the Museum - seconds away, car parking there seemed a little open in a not nice area and I was glad my car was locked away at the hotel.

  5. Yes as per Jerrytr5 instructions require a thermostat with a bypass bleed hole in order that pump is not dead-heading. Problem is that the pulses to the pump are not variable as in a mechanical pump where the pump revolutions are broadly in line with the fuel being burnt and heat to be dissipated. Now if the Davies Craig had a similar revs feed back circuit instead of a one-speed pump (albeit either pulsing or full )  it would be ideal for any car.

    I fitted the electronic version and now it sits forelornly on my shelf.

  6. I fitted a Davies Craig 80 pump to my Stag, after about a year I rtemoved it and fitted an external mechanical pump kit. The electric pump worked well, too well and the engine never got to temperature, It would get reasonably warm but never hot so the heater was ineffective and i understand a warm engine is not running well.  On a damp day the demister just wouldn't demist at all.  I tried to restrict the thermostat bleed but that is not recommended for the electric pump and didn't make much difference. The mechanical pump though worked just as expected.

  7. Metering unit is controlled by vacuum, no vacuum -full stroke  (rich), high vacuum - fully weak. So if the servo is leaking the metering unit will be supplying more fuel and making a richer mixture. How much richer depends on how much the servo is leaking.

    Has the servo rusted through at the bottom?

  8. I have a lot of brick drive, and I have tried many products over the years none of them worked satisfactorily. The best areas are those with a heavy footfall or vehicle traffic and getting a constant scuffing.
