  1. Newlands Corner today....
  2. I went there for the belt check and remembered I still had to do the Trunions. Well it was on the ramp, a 2 minute job and he already had the gun ready, made perfect sense to save some time. I have never seen the correct Lotus cantilever Burroughs gauge until today it has only one mark at 95 and a safe band above and below. What was remarkable was it was tensioned exactly to the mark, I mean exact not even a mm off! I found the Krikit erratic and inconsistent, probably because there is a belt align ridge on my version. Having proved it works and for simplicity I will only use the frequency
  3. Update New tensioner bearing fitted. I tensioned the belt for the first time using frequency and feel rather than the Burroughs gauge. I used the Gates Carbon drive frequency App for bicycles. At 30 degrees before TDC I tensioned the belt to 100 Hz. Being paranoid I then took the car to Tim at Lakeside engineering near Woking. Anyone around the area go no further than Tim. He is a real enthusiast Lotus trained expert. Whats more he has the correct cantilever Burroughs gauge. I was surprised, my tension was exactly on the single line marked on the gauge! Happy days. He then kindly topped u
  4. Yes, when I measured and shimmed them they were all spot on. I checked and double checked, I have a lot of practice at this now! The tappets were noisy only on the rear of the engine. I took it apart and found the clearances on the end two had increased, but from memory only about 1 thou. Maybe because everything is new it had bedded in after 700 miles. Anyway I put thicker shims in and its perfect, no tappet noise.
  5. I now use stickersinternational, but they are Uk based I see you are in the netherlands. The correct graphic is on the manual front. If yo7 send them a PDF I am sure they can recreate it for you. Unless they have updated them recently the usual suspects are supplying the wrong graphic in the decal, but probably only a handful of us would know.
  6. If anyone is thinking of replacing the original limiter rotor arm I have just received a shallow replacement from PNM engineering. The normal size Lucas won’t fit.Be sure and ask them before your order. Can’t believe the speed at which they are getting parts out these days. I ordered in the afternoon and received it the next day, only having paid for first class post. Well done PNM and thanks! Well just as it was going so well I have detected an unusual noise when the engine warms up. It sounds like a bearing. I used a stethoscope and believed it was from the reconditioned alternator. I dis
  7. I have just bought a Kriket one. I found some info on here that says 95 on the Burroughs gauge equals 55 on the Kriket. The problem is the Burroughs 95 = 95 lbs. the Kriket has a pounds scale, so why is the setting on the Kriket not 95 lbs? Maybe older ones were calibrated in units?
  8. The bearings are one of the easier jobs. Heat the hub and freeze the bearing, just dropped in very easily for me.
  9. A decent engineering firm will easily drill it out for you.
  10. Thanks Dave. Steve, Interesting point. The only changes made were float height and choke. When I tune these cars I always found on my S1 there is a position on the idle mixture screw that gives a big boost in power output. Its not very wide probably in the 1/4 turn range. On my turbo I have never been able to reproduce this effect to the same extent. I noticed this time when I tuned it I was able to locate the position and the effect was similar to the S1. Was this due to a change in float height? I don’t really know. All I can say is its now running perfectly. I would know for sure If I swi
  11. Still can’t believe what effect changing the choke size has had. My S1 has always drove extremely well and set the bar. I would say now the Turbo drives even better than the S1. Its a relief after so long to have perfected the acceleration. Your always scratching around in a no mans land with these changes.
