OK Barney's 1293 is not going bad, but he's a bit lean between idle and 3500rpm. From there to 7000 it's all go-go-go.
Cam is a Tighe 104, he has ToyoMini (ie Corolla) 1.46:1 rockers & rimflo valves.
Needles in now are #6. I has CP4s in but the #6 are better up high.
So, all you guys with a Fuzzpack Cooper S, what needles are you running?
Greig Malaure says I may have to get the file out. I have some `needle files'..

Stop Licking the Dog...I Don't Care Who Started It

Haven't quite finished rebuilding my HS4's for my 1275A+ plus.020 but I am putting in BG needles to initial start with as I am told these are the basic COP needles they used.

Karcraft told me it was CP4s they used...??
I know there was some needle confusion at the time....

Vizard suggests #3 or #4.

I think I'll try #3 next, as I have a pair.

You could try any number of these needles,,,they all will produce a richer bottom end than the CP4s or MMEs or #6 type needles

AS

CS1

FG

P6

R6

RLB

RLS

You should put your heart & soul into everything you do.

Has any body tryed this program I have downloaded it but not sure how accurate it would be it lets you put your mods in and gives you a suggested needle size.

Yeah I have and It worked a treat and Still have not quite found the correct one for my HIF as it still lean down low and lacks the torque. The othere needles all have a richer top end and I do not want it any richer up there.

A Bloody Mini

1970 Mini K, 1380cc, 1.75 HIF SU, 30 70 Cam, 2" Zorts
1969 Mini K, Stock Standard and Orginal. (Slow as Hell)

OK Barney finally got his problem sorted today with the help of GR's fuel/air meter.
His #6 needles in the HS4s were spot on.
It was actually going real rich (reading around 10 or 11) between idle and 3000 rpm, as the 20W/50 oil was restricting the SU pistons from rising.
Drained the oil out, he's running fine now, with NO damping at all...

OK at the risk of sounding like a dick is a HS4 the same as a 1' 1/2 su or 1" 1/4
Or is not a SU at all.

Just when I was gunna donate my old needle files to use....he sorts it out

I won't ask why the twenny dubya fifty was in their Doc....somethings ya just don't ask

We have a member here with an ex-Police Cooper S MKII....I will try and find out what needles he is running (may be a lost cause after all these years...most probably fiddled with)

Doorlady, an HS4 is an SU, 1-1/2".

Mick, I put the 20W50 in... had to start somewhere. No flats spots now with them empty, so it can stay like that for a while.
