I'VE HAD TWO SPIDERBOX'S WITH THE SAME CARB THAT WOULD START AND IDLE FINE , AND REV UP-ONLY ON JACKSTANDS , WOULD SPUTTER AND DIE UNDER LOAD . THE MAIN NEEDLE HAS NO ADJUSTMENT PROVISION , SO AS AN EXPERAMENT I REMOVED NEEDLE FROM HOLDER AND INSTALLED THREE TINY WASHERS UNDER HEAD OF NEEDLE TO RAISE IT - FATTER RICHER MIXTURE , THEY BOTH RAN PERFECT AFTER THAT, SO I LEFT THEM THAT WAY AND RODE THEM FOR TWO YEARS TILL I SOLD THEM . TRIED ONE TWO AND THREE WASHER COMBINATIONS . WHAT I USED AS WASHERS WERE ACTUALLY TINY CRIMP ON EYELETS I JUST SNIPPED OFF WITH SIDE CUTTERS . MY KING COBRA 150 WOULD SPUTTER AT HIGH RPM , THAT TOOK ONE WASHER RUNS EXCELLENT NOW - REDNECK TECH.
