Hello,
has anybody already repaired a 1,7`s solex carb?
My engine stumbles slightly when the second system opens (part load transition)
I can`t find any screw to set the second system. What do yo mean?

cheers Matthias

Matthias, I suggest you look at the PDF avaiiable in this section.

It should keep you busy until Mac comes along.
