  1. Oliver, I fitted a 123 to my 4A fourteen years ago and have had not a moment's trouble with it since, although as belt and braces I always carry the original Lucas distributor assembly on board just in case, it would take only a few minutes to swap. I chose Curve 7 to try first as recommended for an engine in pretty standard tune as mine is. It proved so good I stuck with it. Pick up is excellent throughout the rev range and the idle is smooth. The car will run happily on the level at 32kph in top gear and if the throtte is floored it will pick up without hesitation or any pinking. Advance is
  2. I had the stuck wheel problem with the wife's Jazz the first time I had to remove one. I simply replaced all the nuts, left them just hand tight then allowed the car to run back down our drive before stamping on the brake, the wheel shocked free easily. Have used Copaslip ever since of course. Tim
  3. After a short run the other day I spotted something sitting between the scuttle top panel and bonnet. On investigation it turned out I had been driving a TRIU PH, the 'M' having come adrift but very fortunately become lodged as described rather than lost. My fault for being a cheapskate I guess, rather than using the correct clips I had employed pieces of outer insulation from some electrical cable which had an appropriate i.d. I need to revisit this. It turns out I am in good company, in an episode of the Antiques Road Trip, referred to in another current thread, SMK 313F lost the letter
  4. Stan, whilst the straight ahead arrow might look a bit bizarre at first sight the road ahead is a dual carriageway. A right turn arrow might encourage an unobservant driver who had not travelled this road before and who had missed the sign 'Dual carriageway ahead' on the approach to the junction to turn immediately right down the 'wrong' carriageway. Rob, a fair point of course if one is driving a box van, Lotus Europa or similar exotic with a limited rear three quarter vision and one should position for the best view but i won't wear this excuse in this case. I could clearly see the dr
  5. OK so this wasn't taken from the TR but I couldn't resist posting an image from a recent short trip. You might think that the driver in front made a very late decision to turn left rather than right but I am afraid even that thin excuse is not available, since they were signalling their intention to turn left for at least 100 yards on the approach to the junction! I am of course used to seeing such thoughtless driving but the recent acquisition of a dash cam allows me to record and keep such examples for my continued amusement. Tim
  6. In 40 odd years I had Bob's problem of sudden oil pressure loss twice. The first time I stopped the car immediately and checked it over, the oil level was fine and there had ben no untoward noises or exhaust smoke/steam accompanying the pressure loss. I restarted the engine and drove home about ten miles using minimal revs with the gauge showing about 15psi. The following morning I started the engine and immediately had full pressure and I reasoned that maybe the PRV had been held open by some foreign matter that had been blown out when I started the engine with cold oil. I later removed the
  7. Beautiful John. Roll on Christmas 2022 and let's hope Sue and I are allowed back in Australia by then! Tim
  8. I have never had external mirrors on the 4A, preferring the clean lines without them and since they were not fitted when the car was new they are not legally required. I have a TR6 interior mirror, which not only offers a dipping function but also a usefully wider field of view than offered by the original 'postage stamp' type of the 4A. Having the Surrey model with wrap around rear screen I have almost 360 degrees vision and a quick look over either shoulder is enough to check the blind spots. Tim
  9. I have a very strong rare earth magnet on the sump just above the drain plug. I don't know if it ever catches anything since after a run to warm the oil I of course remove the magnet before draining. I also have a magnetic drain plug and am pleased to say at each oil change I find very little swarf on it and then only tiny particles.
  10. Why place the magnets on the rear sump face Roger, is it to be closest to the pump filter? Tim
  11. Thanks Andy. Some time ago I monitored the temperature of the water in the top hose as the car warmed up at idle when stationary and noted that 'N' on the temperature gauge corresponded to 92 degs C, very close to the nominal rating of the thermostat. This was at a point where I should have been getting full flow through the thermostat and I found the agreement encouraging. I had previously tested the stat in a saucepan of water when SWMBO was out and found it to start opening at ~85degs and to be fully open at ~90. I was happy with that crude test. I think the voltage stabiliser is OK, I have
  12. Is it a good idea to drain some coolant before slackening the head nuts? It is very 'seaching' and is there not a chance some might enter the cylinders by capillary action? Tim
  13. I dispensed with my radiator duct/cowl 40 years ago when I fitted a Kenlowe in front of the radiator, simply because it would have required butchering to accommodate the fan motor mountings. I know the received wisdom is that the duct aids cooling by concentrating the ram air flow through the radiator. My issue is that for most of the year with a functioning 91 deg C thermostat I have trouble getting the engine hot enough so a duct would only make matters worse on my car. At the moment I am running with half the rad blanked off and the temperature gauge doesn't reach half way in normal running
  14. Does anyone know of a competent company that could install security cameras to monitor the car park of a block of flats in Luton, Beds? Ideally they should be located in the Beds/Herts area. many thanks. Tim
  15. Yes, hindsight is wonderful. Whenever I dismantle something that is not self evident, e.g carburettors and linkages I take digital images for reference. Tim
  16. Not sure the actual spacing washer positions could be seen in that picture John. I would have thought that the positions would be those that ensured that all rockers acted as centrally as possible on the valve stems. On my 4A when the valve gear was last overhauled I used some additional shimming washers to achieve this condition. Tim
  17. I guess it all depends on whether that inch is in the legs or trunk Stuart! I know someone the same overall height as me who has trouble finding enough headroom in most cars because his legs are relatively short and his upper body disproportionate! Tim
  18. Those brackets do indeed look well thought out and robust but I reckon if I tried them with MX5 seats in my 4A then at 6'3" my head would be bouncing on the hard top! I am very happy with early Federal TR6 seats that fit straight on to the existing 4A runners, just requiring catch plates to be fitted to engage with the safety mechanisms. Tim
  19. Up on compression stroke! Tim
  20. Thanks Stuart, I never knew that. As a matter of interest do you know when the provision for a reversing light switch on the gearbox top cover was first made? I fitted Wipac reversing lights, preferring these to the TR5 type since they needed only two tiny holes for the wires rather than a socking great one in the middle! Tim
