If one of your jets has a larger hole than the other, it's worn out. Replace it.

DX needles work quite well on "bigger than normal" Volvo OHV motors, and are commonly available (RPR, for instance).

SU carbs make great barometers... you can expect to retune the mixture for every few thousand feet of elevation -- but the right needles will pretty much be the right needles for any particular motor. You just need to raise or lower them as needed.
