  1. Has anyone got the part number for the Yaris steering column? I have been looking and there seems to be a lot of similar parts with different part numbers ending in 40 to around 52
  2. Is this group buy still current? I haven’t been on the Forun in a long time and I need a manifold for 91 carb turbo
  3. Been away so haven't had chance to re look at timing and the valve thing in right quarter panel. workshop manuals and electrical diagrams on back order from Lotus unfortunately so I'm working on limited information.
  4. This appears to make a lot of sense now, not near the car but I'm guessing the changeover valve is the odd thing inside the rear quarter pael near the fuel release solenoid. Pretty sure the hoses are correct. I'm guessing it is controlled by one of the temp sensors in the Alu pipe? Do all these switch at the same temp? Maybe I have the wire pairs to wrong switch? you just have to admire the simplicity of an Esprit ?
  5. Flywheel and cam timing appear right, I thought it was carb trouble but now looking more like ignition timing, I still don't understand why it changes after a few minutes of warming up and idle rpm drops. Thought this was jacking solenoid but it's the same with throttle Jack taken out of the equation so must be something else that changes with temp or a timer? Is there a temp sensor that interacts with ignition timing? if so it would explain the dramatic change after a few minutes warming up.
  6. This is sounding possible, I've been trying to work out why it seems ok for a few minutes, then revs drop and runs poorly when warmed up.
  7. Ordered workshop manual and electrical diagrams from SJ. dont know why I didn't get them ages ago
  8. New fuel pump, filters, breathers, tanks cleaned and sealed etc. just noticed something very weird, the high idle for first couple of minutes is not by the jacking solenoid because it's not even close, so something else, timing etc is holding high idle for so long. While in high idle it will Rev no problem, as soon as idle drops (can't see why it would time-out etc) then it won't Rev at all. i can usually fix most cranes and other technical machines in minutes but this is baffling me at the moment
  9. Stevens car, I appreciate that could be blasphemy in this forum but it's a carb turbo so a bit of a rarity in the 'other' side. after almost 8 years it's almost back in. Running order but I have some running issues which is puzzling me. starts no problem, high tick over for first few minutes, during which time it appears to run pretty well. when the RPM drops to, it still idles fine but will not Rev at all, struggles, pops bangs or cuts out etc. figured it must be carbs so had them rebuilt b specialist, still the same. (Appreciate they will need setting up). noticed the problem was much less when plenum box was not fitted so maybe turbo? - nope, that's ok. all hoses and vac pipes are new and in right place, just feels like I'm running around in circles and it's getting frustrating because I'm so close to it being drivable again. any suggestions guys?
  10. Thank you! That's a massive load of my mind
  11. This may be the most stupid question ever but I can't find an answer. After several years I have finally got the engine back in the car following a complete strip and rebuild. Starts, but only just and doesn't run well. The only thing I can think of now is if I have somehow managed to get the Inlet and Exhaust cams reversed. Is this possible? The valves are all closed at TDC, timing marks lined up etc etc. How can I identify (while in the car) which cam in Inlet or Exhaust? This one has me stumped.
  12. Has anyone been able to find an alternative, or even a similar unit that can be modified.
  13. According to the diagrams on the parts manual: carb turbo cars have a simple pump and filter, while the USA and `other` models have primary, secondary and accumulators etc. Just wondering why my 91 carb turbo has all the extras? Is it ok to remove these? the secondary pump is a nasty plastic Italian item and since i am rebuilding / replacing everything i want it all right. Purchased a Walbro high spec pump for the primary and then realised there was a secondary as well along with the filter and what appears to be a shut off of some kind. - pressumabley over boost cut.
