Insane, at least if not worse

Sounds like you are making strong progress and a win is in sight 

It certainly sounds fierce!

The Distributors have different advance Springs and weights. I Plan to take the lightest weight for a first atempt. Megajolt?

Megajolt, or something like it is the best answer (if TUV allows?) but not the easiest or cheapest.

Or is it possible to get this distributor with a version of the 123-Tune inside it?

What shape curve do you want to have?

[Martin]

123 Dizzy is available, but at a price. 600 Euro. 
So try  and error?  Getting the curve starting  from around 5 degrees at idle. Then 12 .. 15 degrees Up to 4000 , ending  up with 30 degrees above  5000.

Thoroughly unreasonable!

Are you aware of this?

No personal experience, but it looks like it could do what you need and not quite so expensive

Light weight, strong spring for the second stage then......

[Martin]

I know the Aldon device. I still have an Accusparc programmable ignition. Runs on Win 7  Asked Accuspark already  whether a programm for Win 10 is available. 

Had it for the Mini of my son, but now unused on the shelf.

 Perhaps I will lighten the weights with a drill first

I take it you have tried installing it on your Win10 machine, using the option to run as Win 7? It's a while since I last tried this but I seem to recall it worked for whatever I was doing at the time? Apologies if you are already ahead of me btw!

After playing with various Jets, ignition timing and tweaking with the carbs I have still a lean mixture  between 2500 and 4000 when cruising. But this was no excuse. Today a kind of Track day at the Nürburgring. For 2 hours only Cars, minimum 30 years old on the track. No cruising below 4000 

The car was great. Brake excellent. After some laps a bit sailing over the front. Nankang NS 2r. First time I drove these tyres. No experience so far with the tyre pressure.

It was fun fun fun and fun. 
 

[Nick Jones]

 

Excellent!

After "some" laps....... 

Car is home again..... how long since you last drove it there?

[Martin]

With that car, last race October 1988. Then Martin and car retired.

Good to have you both back 

[Martin]

lousy quality.

 

 

 

[Martin]

That lean area between 2000 and 4000 was upsetting me. Thus I thought  some bigger idle jet would be good (27 Euro for 4 ouch). But then I thought and googled a bit. The idle jet does not only cover the idle mixture, but in addition is responsible for the mixture between idle and part throttle operation. There are so called progression holes that enrichen the mixture after slightly touching the throttle. What I had not recognized so far was that there are different sizes of progression holes. 

Two pictures. Weber DCOE in the GT6, which is running perfectly from idle to full throttle.

And from the Polo, with a lean spot / area.

 

[Martin]

The first hole towards the engine is the same in both carbs, appr. 1mm.

In the GT6 then both holes are 1.6mm

In the Polo both are 1mm.

Thus I removed the carbs, drilled the two holes in the Polo with 1.5mm.

Other car. Lambda is now in the tick over / part throttle area between 0,85 and 0,9. Car runs smoothly (taking into account the 316 degrees cam).

Now only too rich at full throttle, but there I have to work on a slightly smaller main jet. The bigger idle jets not needed. 

Fun to drive

Brave man. However glad it has sorted the issue 

[Nick Jones]

Smart …..

Dave (the original Mr Sideways) used to get excited about progression holes (more of a thing on Dellortos than Weber’s IIRC). There’s at least one (old!) thread on here on the subject.

[Martin]

forgot to add this years outing 

[Nick Jones]

Great to see it getting used 

Do you use it on the road too?

[Martin]

At present not used often. Unfortunately all of my classics not so much in use. Sometimes I think I should sell one or two cars. But which ones? I like them all. 

[Nick Jones]

I know what you mean. Even with just two classics it is a bit of a challenge to keep them exercised and in top condition.  Especially when the “modern” fleet is old and demanding….
 

What is your full list these days?

GT6 Mk 2
Vitesse estate
Polo
Mini (x2?)

what have I missed?

My solution to this has been to gradually do away with the 'modern' fleet, replacing them with classics.

I'm not sure I'm a ringing endorsement for this as an approach though, seeing as only one is on the road at the moment

I know how you feel! A house move has prompted a rationalisation of my hoard of projects, which is no bad thing and is way overdue, but choosing which ones get the chop is a tricky decision...

[Martin]

  the list of the fleet, youngest first, my cars :

2004 Volvo 70 D5

2003 Hyundai Getz 1.1

1991 E30 325 convertible

1988 Mini 1.0 City e

1977 VW Polo

1975 Spitfire 1500

1970 GT 6 MK2

1969 Herald Estate converted to Vitesse MK2 drivetrain

Son has

2008 Fiesta 1.4 16v

1992 E36 318 , modified for track days, 328 conversion planned

1975 Innocenti Mini Cooper

Wife has

1998 Suzuki Vitara 

 

[Nick Jones]

Hah… I knew I had forgotten some! That’s quite a list. E30 is basically just a slightly improved Vitesse….

My “modern” is 28 years old…. Does that count?
