  1. You could possibly adjust your pressure release valve to get a bit more pressure at 2000 RPM (about 70). Tubular manifolds do get very hot, although when I had them on my GT6 I only saw them cherry red hot when thge timing was a bit off. I have always wondered with exhaust wraps whether they would create a very hot spot at the first unwrapped section. Andy
  2. No, it isn't. Have you got the air out of the system as per earlier posts? What is the temp in the radiator neck when the gauge is showing hot? andy
  3. I posted in your out of date thread. I think your new pump is not up to scratch, maybe vane clearances. revert to old pump and 20w50 mineral and I suspect things will be back up to normal. Andy
  4. Paul, if I have followed this correctly the one thing you haven't done is run it with your old pump and 20w50 mineral? Andy
  5. Even better, get the front of the car into the air while you run it up to temp with the rad cap off, so that the top of the rad is higher than any other part of the coolant system. Or do it facing uphill. if you still experience problems after this, buy a 5 pound multimeter from Maplins with a themocouple on it, run the car up to temp with the rad cap off, compare the temp on the multimeter with the "high" reading on the gauge. Andy
  6. AS Ian says, I would spare yourself the effort and just get some of the strengthening plates available from Revington. I don't have a part number, i think they may be a TR6 part. If you use those then I would also get 4* lower fulcrum brackets with extra long studs from Revington - Part No. RTR3287 You should also, of course, make sure that you have had the radiused strengthening brackets welded in and that the welds are still good. Andy
  7. The crank turns clockwise as you look from the front. So the pulley scale to the right of the TDC mark is BTDC, looking from the front. You may find this useful http://myweb.tiscali.co.uk/tlweb/tr6/injection/pi_cards/card_1.htm Andy
  8. The engine is "dieselling" http://en.wikipedia.org/wiki/Dieseling , either the mixture is too lean or your timing is too far advanced. Or, possibly, if you have installed new spark plugs they are rated too "hot" eg NGK BP5HS instead of BP6HS. What do the spark plugs look like after a run? Andy
  9. and held the pressure relief valve open? not impossible. Andy

    Tyre Choice

    If you go higher than 185/70 you will lose much of what makes the IRS cars good to drive. The car will feel "floaty" and when the rear goes it will do quickly, whereas with the thinner tyres the rear contact patch changes much more progressively. Andy
  11. Ash look at the right hand side of the hole, it is 2mm short from being flush, as Jesus pointed out in his original post. Andy
  12. chaps look at the picture - with the needle set like that in the piston it is the same effect as having the jet turned down 2 or 3mm too far andy
  13. Hi, in your picture the needle in the piston must be flush with with the piston face. if it isn't, it will be like running with choke [ie lowered jets] all the time, which accounts for your high CO reading. Andy
  14. if you go with a wider tyre you will end up with a car that is worse to drive, IMHO. I had 195/65 on my 4A and the feel was awful. Andy
