The final adjustment is done by observing the shift points. If the cable doesn't hit an internal stop in the transmission slightly beyond the wide-open position on the throttle, you've probably made a mistake in the spacing from the carb to the cable support bracket. The main concern is to have enough throttle pressure to prevent slippage on the upshift, yet allow the trans to shift back to 1st. gear at a stop. I'd suggest running a bit more pressure than you think is necessary (cable pulled out of the trans a little too far) and drop the adjustment back toward the carb a notch at a time until it shifts right.
