I just bought a swell second-hand Uni-syn from John at Aircooled (thanks, John!). In order to use it on these Kadron-Solex carburetors, I have the little matter of the air filter stud sticking up right in the way. John's article on synchronizing dual carbs mentions a work-around: using a cut-off chunk of a Pringle's tube to space the Uni-syn above the carb. Alas, in the Wonderbus, there is not sufficient room above the carb for a tube and the Uni-syn unless I cut a hole in the engine room's overhead.
Before I grab that air filter stud with my Vicegrips and try to turn it out, I'd like to know if that stud is threaded into the carb, or if it is a press-fit? Haven't been able to find a good parts diagram of the carb.
