  1. It's been a number of years since I was into a clutch slave cylinder but as I recall the rod pushes directly on the piston, not on a piece of black plastic.
  2. I suspect the "round black cup" is a seal to keep the piston in the cylinder and is supposed to be removed before installation. I'd contact the dealer or manufacturer.
  3. My first guess would be a leaking intake valve seal. You might be able to visually inspect the seals with the valve cover off and a bright light. I'd do a compression test on all the cylinders to see if #1 is significantly (10%-15%) lower than the others.
  4. I'd mic the crankshaft journals and the cylinder walls before making a decision.
  5. If the fan clutch appears to be working properly, I think ceramic coated headers may help. Cliff reports the carbs staying cool to the touch using ceramic headers. If it were mine, I'd also pull a freeze plug or two to check the coolant passages for corrosion and build up. No one knows knows if Cal. Datsun ever cleaned the coolant passages in the block?
  6. Contempt is just another negative emotion that can be aimed at anyone based on our own beliefs or unfulfilled expectations. It's based in judgmentalism and comes from our ego. It's not an admirable trait.
  7. Having worked with the homeless for a few years I can verify that those people who have the least are some of the most generous people I've met in my life. That said we all need to work on our contempt for others.
  8. That shows my ignorance about electric fans. I've never dealt with them. Members here may have recommendations or check out the discussions over at HybridZ for advice. The only time I had an issue with overheating was solved by re-coring the rad and adding another row. When my fan clutch froze up I replaced it with a flex fan. Never a problem after that.
  9. Will this be the final and concrete solution to your problem? No one here has a crystal ball as far as know and if they did they'd be looking for that unrusted barn find Z that most of us know is out there somewhere. The shrouded fan(s) would seem to be the best solution, IMO, but but there has been some discussion at HybridZ lately about upgrading the alternator when using double fans.
  10. I hadn't thought of that. Removing a float bowl top and having a peek inside would confirm fuel evaporation.
  11. 3 - 4 psi should work on most carbs. A fuel pressure and fuel volume test will tell you if the pump is working properly. I'd also pull the floats and needle valves and clean everything.
  12. I like the simplicity and driveability of the SUs. Weber's would be fun to fool around with but I'd want a Dyno to check the tuning of them.
  13. No tools needed to remove parts, just give the cars a good shake.
