S&S L Series carburetor remains one of my all time favourite carbs, right up there with the magical bronze spawns of Adolf Linkert and the wonderful aluminium offsprings of George Riley.Now they’re completely rebuilt with new throttle discs, shafts and bushings, I cooked up all new idle tubes and installed new main jets. I also relieved the top idle tube passage for the low speed circuits since this is a dual carb set-up I thought that could be a positive thing.
Soldering the floats in place and then tweaking the little lever to make the floats float at just the right level is a time consuming process to say the least, it’s good fun though, at least at this point, redoing this on a hot engine during a hot day with a hot temper getting drenched in gas is not quite as fun.
Anyone who’s worked on some of those carbs know how bad the floats usually are. These original floats were a bit banged up but nothing too serious, but I still troubled my tiny little mind with them for a bit straightening them out and making sure they don’t leak.
Observe the carved horizontal line at the top of the float bowl, that’s the line you use to measure from down to the top of the float, in the GBL manual you can get the right measurements, where it’s suppose to open and where it’s supposed to close. But if you study the lines and shape of the floats this is kinda far from an exact science.
Now, since this is a dual carburetor set-up I kept the float levels just a tad on the lean side to save Jerry’s Knuckle from getting soaked in gas.
I just love the look of these... Pretty much like two Linkert DC's on steroids.
Or maybe a bit more like two Linkert DC’s on mushrooms..?
