46mm SUs on an L20B

[docbainey]

Scored some Z round tops today, I was wondering if anybody has done the same. Need some tuning info. I had 2000 carbs on my 610 in the early 80s with no tuning on a stock L20B and it ran kinda rich, livened it up though. Then I built the car to ITB spec, cage included to this day, so I offed the manifold & carbs (what a dope!) Anyways, what nozzeles and needles should I be close to. I got the Weber 32/36 or whatever it is on now. Driving on the street primarly, 19 miles the last 3 years, so ITB is out now, looking at some increased stret performance cheap. Lookin to put together a good low end motor. Probably Z22 crank @ an 85mm bore, light cam, header. I just need some numbers for needles and nozzles that work well, what a ramble!

 

Thanx!

What needles are in the SUs now?

Most likely need some fatter ones due to the smaller displacement of the L20.

Have a manifold?

Stock 510/38mm SU linkage will not work.....L6 can be shortened to fit.

I have RN needles...very thin (rich)...not sure if they will work on my LZ23 yet

The SUs are in transit. I don't have a manifold yet. The carbs are coming with a Z manifold, I'll probably look at chopin it up and doing some welding.

Volvo B20B (2 liter) with twin HS6's used KN needle. Should be quit close.

He later ran 40mm webers I think and was alot better

You can buy needles from Z Therapy last I checked.

Go to master price list and then look under 240z... I think that they are $30 for the pair.
