It is so flipping hot here that we can neither of us be bothered to go down to the pool.
This sounds mad, but we made the decision from the off to not have one you can nearly, or even probably, dive into from the living room french doors.
I'd...
Yes, I am heeding what both you and @landowner and others are saying. It is a 50 year old Mini with A-Series technology with no ECU etc. etc. I only need to get it running sweet not "perfect". That'll do me fine. I am pleased to have got it...
On what is likely to be a final remark to do with this as I think you have got it aabout right now, this trubble you have had reminds me very vividly of the same trouble, sort of, that I had with W's Porsche copy kit car.
The engine was a tuned...
It gets complicated when you try too hard to make things perfect, ... it's a Mini :)
Did you find out if you have a 10 deg dizzy ? If so set timing so you have over 30 deg at 4000rpm but no more than 35.
If it pinks low down then you have the...
Did I?
I thought I just said that I thought the rolling road guy was a cowboy.
If he tunes engines as you say, then apart from the exhaust analyser, then he is doing it the same way as I would.
I don't have a Snap-on strobe, my strobe is a Gunson...
So, up at dawn this morning to make a start on the apple harvest.
Dreadful this year compared to last.
We will get a fairish bit of juice but nowhere near the bumper crop we had last year. We still have stuff to spare in both countries. Good...
Sorry, the pic of that plug was from the guy AC DODD who you professed a dislike for. His day job is tuning SU carb'd engines.
I am going to be doing a bit more miles tomorrow going to that show so I will pull the plugs after that round trip...
100 thou. So 1/10 of an inch. Without measuring it, just looking at by eye on your pic, that looks to me a bit more than that.
Just saying. Have you actually measured it?
And I am not sure who you are referring to, is it you, being ironic about...
I know the jet does not move, the jet should only be used to set the idle mixture only. But if you go hog-wild and wind it down too far you affect more than just the idle mixture, you affect the first few station positions too. :(
@Stanleysteamer well, well, well. Here is our SU carb "expert tuner" showing us all a perfect plug after a tuning session.
Just like the guy in the YT clip advised look at the fire mark/band on the earth strap of the plug. 100thou' band just...
Yes I know. If you wind the jet DOWN the mixture is enriched across the entire needle profile as the needle moves up and down.
Contouring the needle at the relevant "stations" affects the mixture at the station-specific rev-range.
The needle...
Just a thought, the jet in an SU isn't adjustable
All the jets are the same size and fixed in HIF 38 carb for instance, just have different needles for different cars
I had noticed that the pre-ignition "bang" seemed to always occur when trying to accelerate from a low (15-20) speed. I know generally how the SU carb works and I realised that if the throttle was suddenly opened that the dashpot would rise and...
