  1. IMHO, short of dripping wet I don't find plug appearance to be a great way to judge fuel/air for 4 stroke motors. Having said that, if those plugs came out of a 2 stroke I would say yes, lean.
  2. I've been taking notes of your planned engine build and I've got a lot of pictures of CatKong so a little hands-on would turn piracy into collaboration.
  3. Glad to actually have a little info to share back. If there is a future where I replace the current pump, I would go external too for all of the reasons mentioned.
  4. Assuming Caterham is using the same pump consistently, yours will be from an earlier European spec Ford Focus, part number BV61-9H307. My understanding is the ECU controls the pump voltage rather than a mechanical regulator.
  5. I'd take a look at the pins in that connector. I say this from experience - from the factory I had a pin that wasn't properly seated so even though the connection was solid the electrical contact was not.
  6. Have you tried going upstream of the spark plug coils to where they connect to the harness? A loose connection there would account for losing one or more cylinders due to vibration.
  7. I don't recall the difference off the top of my head, but do recall that the diameter difference between the 13" and 15" option as being small since the 13" uses a taller tire sidewall.
  8. Maybe (likely) disappearing from the new car market, but I believe the collector and competitive enthusiasts will be able to buy petrol for some time to come. There is a car show here in the Seattle area in June that usually has a few hundred cars and trucks of all kinds covering multiple city blocks. Every year there is a handful of battery converted cars and trucks from back when doing so would have been truly novel. Maybe after I'm long gone that show will feature electric vehicles with a handful of oddball petrol samples. Heck, maybe the future will have someone converting
  9. My Caterham and I have our first opportunity to spend some time on a track, and I'm wondering how important it is to swap the windscreen with an aeroscreen? I'll trailer the car to the track, and have a full-face helmet and an aeroscreen, but for the occasional track use I'm wondering when/if it makes sense to do the swap given the vast majority of time the windscreen is needed for the street. I'm assuming the primary reason to take the windscreen off is to protect it from destruction, and secondarily having a flat pane of glass at a right angle to the direction of movement might
  10. I did for grins, using a very small edge trim around the entire perimeter of both the upper and lower openings. Totally not needed, not often done from what I can tell, but it was COVID and I was looking for anything to make the build take longer.
  11. I've got a question about the idle situation borne of both ignorance and curiosity. When the IAC is doing its thing, is it bypassing or operating the butterflies? I'm wondering if the butterflies are moving during the runaway revs...
  12. Maybe I'm just saying the obvious, but the reply indicates they think Caterham is importing vehicles - they are importing kits not cars. It sounds to me like the kit part of the equation has been left out.
  13. My assumption would be the ECU is unlocked, but the mention of the mapping kit only seems to refer to diagnosis rather than changes. I would just be doubly sure that what they send is something you can have someone local to you tune.
