I bought a 34/34 from ebay and this guy at reline carbs says that it is a solex? which is no big deal. There seems to be two fule jet mixture screws. (the little blak screw at the base of the carb). Is that the idle mixture for the primary and the secondary? And which is tht primary the drivers or passengers? I'm pretty sure that I need to rejet it either way.
