If I had 1 pair running lean I'd look at the carbs, but both failing with similar faults at the same time. I fully rebuilt the carbs just before the engine build, bodies faced and bushed for new spindles. Jets converted to old style (no wax stats) I'll check them over before I spend a fortune of an electric fuel pump setup, but I just don't see it being the likely cause.

So, with the distance of hind-sight I'm starting to think that the car/engine was running progressively leaner over the last 2 years. Before the 2023 RBRR it had a rolling road session, and at top RPM it started to lean off. I changed the fuel filter for a free-er flowing one and that seemed to fix the issue. Since then the prevalence of what sounded like "pinking" under heavy load/throttle has got progressively worse (and MPG has gone up on long runs) - I should have stopped and thought about it and done some investigation before the RBRR this year. The thing that drives me towards the fuel pump is - what could be a problem that's going to affect both carbs equally. It's not impossible that both carbs have developed the same fault - but I doubt it. So although expensive I'm starting with the most probably cause (IMHO) - the fuel pump.

My electronics stuff is almost completely digital stuff - although I learned about op-amps and stuff at Uni I struggle with the analogues side. Here's my old work-bench for digital:

Sadly 0 progress since my last post. The engine is sitting there in the car without the head and the head is on the bench. Various house projects (kitchen, bathroom, flooring, garden) and some family events (wedding etc.) have soaked up all my time outside work. I might be able to find some time next month to start making progress on the car. I've half decided to bite the bullet and pull the engine (rear crank oil seal needs replacing), take the hood off (force myself to fit the new one I've had for a few years waiting for the time to do the job), drop the diff (to fit the ATB 3.63 unit I built a couple of years ago) and remove the front wings and OSR wing to fit the replacements I have. It's a massive pile of work, but at the moment I just keep putting it all off to another day. I wanna get the car properly fettled. On top of all that - I'm looking at moving to an electric fuel pump as I suspect that a poor performing mechanical pump is the culprit w.r.t. the very lean running.

This. A thousand times or more, this.

I should probably step back, but against my better judgement. It's hard to "agree to disagree" with somebody who (even jokingly) advocates that people like me need shooting @RogerH @Nick Jones, chancers/spivs like Fuckwadge, Trump and even (my opinion) Starmer are about lining their own pockets with money and power. If their owners demand something - that's what they do. They only seek to harm as a distraction from what they are doing or to serve their masters agenda. With Rowling, she just seems to want to harm trans people. I can't speculate or understand her motives, but that seems to be what she wants and the hill she wants to die on. So be it - freedom of speech! Not freedom from consequences. Anti-woke is just a way of saying "it's not fair I want to be a racist/misogynist/transphobe/homophobe/hater without consequence, like I used to be able to", for "grass roots" they want to hate the way they used to, for the powerful it's a superb distraction from the growing power of the wealthy and their constant acquisition of capital/assets. Woke is just being aware of how your words and actions can harm people, and caring. I've mis-gendered people, I was sorry and they accepted it. I've told racist jokes when I was younger, I'm sorry I did and I wouldn't do it again. I care if my actions/speech harm other people. Except fascists and racists and homophobes and transphobes. (See also: https://en.wikipedia.org/wiki/Paradox_of_tolerance) It's never a good day to punch somebody for being black/gay/trans/homosexual, it's always a good day to punch a Nazi.

I need shooting? I'm woke and proud. JK Rowling takes one of the most vulnerable groups in this world and uses her power and wealth to make their lives harder and more dangerous by insisting on a GCSE version of biology that doesn't exist in the real world. People punching DOWN are WRONG. Her version of gender is WRONG. I'm happy to have a difference of opinion with anyone on politics and opinion, but moral right is right, moral wrong is wrong. If you make the lives of vulnerable people harder and more dangerous, I'm not on your side. Would I call for her to suffer physical harm? No. Would I call for people to boycott her works? Absolutely - feeding her wealth and ego can only make things worse.

I don't think anything redeems that POS. He's a chancer, out for himself and his cronies. I tend to avoid political threads online these day, but my position for all it's worth is that Labour are a colossal disappointment, more interested in protecting their backs over Israel and genocide than they are about actually solving this countries problems. Instead of taking a stand on migration and asylum and making positive changes, they have just become "populist light, all the harm of populism without being popular" A very simple capital/wealth tax on residential properties sold for over £2.5 million would generate billions of pounds in tax in the coming years and the mega wealthy wouldn't even notice - instead we pissed off the farmers by closing the loophole that Clarkson and Dyson are openly saying they are using to avoid inheritance tax. Instead of hating Clarkson/Dyson for this, the farmers seem to idolise them and Fuckwadge. Crazy. Exactly how populism works - simple, plausible and WRONG answers to complicated issues. My vote round here is a wasted vote - I won't vote Tory or Re-fascist, and they are the only ones with a chance of winning. I plan on spoiling my ballot in protest over Palestine/Gaza in any upcoming elections unless we ever get PR.

Yes, at first I replaced all the "buttons" and cleaned the old spring. That was better, but only for a short time. Within weeks it was back to before. So I replaced the sprint - it's on Owen Spring from Canleys - quality is good - but ride was too high and that affected camber.

Can't comment on the GT6 mk3 spring - my car had the original 1500 spring and then when I replaced that with a 1500 spring I had trouble with camber and ride height - had to fit a 3/4" lowering block to get it how I wanted it. ok, that's good. And the arm brackets? no signs of movement in/out? Threads/nut look tight/solid?

It's unlikely to be the issue unless they are totally soft/rotten, but I would check by supporting the car under the chassis with the rear wheels "drooping" and us a pry bar to try moving the diff up/down and left/right. If it has significant movement - further investigation required! Another thing to check would be if the bodywork where the radius arms attach isn't flexing.

How are the diff mounting bushes on the Spit?

Gimp will open pdfs.

Cheerful and optimistic soul! 😉 What will be will be.

I was having a chat with @wimpus, he suffered a head gasket failure around the jig holes on #4 at around 6k miles. Since plugging the holes he's done 30k miles without failure. Could be coincidence, but I think I'll play it safe and plug the holes before I rebuild. Thinking about the lean running - I think I might have a fuel pump issue. Back in 2023 there were 2 dyno runs during tuning where the engine suddenly went lean at high RPM. I changed the fuel filter and we then had clean runs for the tuning. I assumed the filter was restricting the flow, but I'm starting to think that the pump has been getting progressively weaker since then. I might replace with an electric pump and avoid the pressure issues with the current crop of mechanical pumps. Will ponder the symptoms/solution.
