  1. Regarding cleanup of your carb casings, I also found that ultrasonic cleaning didn't bring them up as good as I'd like. So I made a home-made soda blasting attachment from an old tyre pressure gun on my compressor. Couple of quid of soda powder from eBay and they came up pretty ok - not quite as good as aqua-blasting though. But the beauty of using soda blasting is that the soda dissolves in water, so a rinse back in the ultrasonic tank and there's no danger of leaving any cleaning media inside. Oh, and a liberal spray of ACF-50 on the carbs and manifold (in fact any exposed alloy) helps to keep the surface corrosion down.
  2. Since the body is off, you can get an idea if any major 'twist' is present by placing a straight edge (4x2 wood works) on top of the front box section, or spanning the front upper shock absorber chassis mountings, and a laser level (one that emits a straight line beam) on the rearmost crossmember and seeing how they line up.
  3. It's only available in the USA as far as I am aware - you'll need to import it or have a buddy over there to get it to you. Jon.
  4. The metal part is a power transistor screwed onto something. Normally they are mounted to a heatsink to dissipate heat from switching loads or amplification. What is it mounted to and where do the wires to it end up ?
  5. Hi Steve. Yes, they are a push fit into the tubes making up the two engine mounts. Its also possible to fit them 'in situ' with the engine still in the car, but needs a good raise of the rear end on sturdy axle stands plus some dexterity with your fingers and small tools to access the mounts as they have to be removed to fit the bushes in them.
  6. I do not recommend the poly bushes for the engine mounts in the early S1 setup. I replaced my (melted just like yours) replacement 'uprated' poly bushes for good old standard equipment rubber ones. Added a heat shield and all has been well for many years.
  7. Ticket bought and downloaded, including the Display Pass. PM'd you the booking ref in case you need it. Cheers, Jon.
  8. Hi Martyn, @JNW3 alerted me to this today - I’m away and no access to book the tickets until late tomorrow evening - any chance I can grab the last space please (S1 Esprit). Let me know. Ta. Jon.
  9. Thanks - that prompted me to check the markings on O-ring box that I used, and they weren't Viton, they are just marked as "Nitrile" which I believe is safe for brake fluid. Phew .. I'l see if I can edit my previous post to avoid mistakes . Nope, can't edit it.
  10. I dismantled the ones on my S1 without issue - had to, because they dripped fluid. I had Big Redd send me a seal overhaul kit which in the end also turned out to be the incorrect size. The important one (which prevents the fluid leaking out of the handbrake lever arm) is the O-ring underneath the plate of the arm. I think I just measured up and ordered a Viton ring of the size from the many suppliers on eBay.
  11. Could the “Eurostile Bold Extended” font be close enough if you have to scratch build the decal?
  12. @philleech I see the Accuspark 'Stealth' black box is showing as discontinued on their website. I wonder why, seemed like a good product ?
