Carb problems, Solex Cisac Z11

Post by n8sh4de » 21 Sep 2016 05:51 pm

I thought that my carb would be running good now, but the car was obviously too slow. (13-14 sec 0-60, '85 360 GLS, B200K)
I've found out that the floating high has a large effect to WOT fueling of the car, so I've tried to adjust it properly tody.

I haven't found a way to get the correct 33,8mm floating height without the ball depressed, even with the ball depressed, the carb floods over.
So maybe the floater is too heavy, it should weight 6g, but how to weight it? The complete device including the brass (I got 8g) without the bushing or just weighting the floaters, holding the brass end of the device(I got 6g)?
I'm starting to hate this damn carb... sm2

IIRC the floats absorb petrol over time so you need a new float as it will be too heavy.

As I understood it is the weight is of the complete float that you need to weigh, without the bush.
There is no need to hold part of the float, this corrupts the measured weight.
Plastic floats are well known to absorb fuel over the years and get heavier.
My advise: replace the float with a new one.

Thanks for the fast answers!

...I've tried to find one, but where to get a new floater?

I wouldn't be surpised if Mac also has one kicking around......

I see that they also have overhauled Z11's now
