Be carefull of getting hung up on HS/LS needle adjustments. Keep in mind that adjusting them is a balancing act. If you adjust one you may have to adjust the other. There are several tests for each needle I like to set both needles to factory settings then use the pinch test on the low side first. Pinch the line feeding the carb and listen for the engine to rev after 2-3 secs. If it revs in 2-3 secs its good if it takes longer its rich if it dies its lean. After that I start playing the high side needle. Ilean to max RPMthen richen a bit. After all that I then run the throttle up a seond time and have someone pick the A/C up tip the nose up and down and ensure it doesn't lean out at severe pitch changes. Ihad an engine that had a leak in the carb and it was hard to T/S it as I was learning how to tune at the same time. It takes time and tinkering to get an engine set right but once its set don't over tinker it.
