Try turning the air screw in .25 turns at a time see if this helps. the two cables to the carb are part of the tors system.
i dont think so cause your getting spark.. i would start by turning air screw down 1/4 at a time give it some time to run each time.. also you can tune it under the seat on the top of the tors. if these two dont help jetting is your next step.. also check float level..
nope, overrevving is usually caused be a lean mix. most likely an air leak somewhere. if the culprit isn't the jetting then you'll need to check and tighten your carb boots, float bowl, head nuts, base nuts and exhaust. if those are all good, then it could be a bad crank seal.
