Just reconnected the governor on my 1985 950 18hp opposed twin Briggs. Had to buy a fabricated throttle link so length may be different the original. I can't get enough speed out of her, when governor kicks in throttle is only about 1/4 open. I moved the spring on the governor's lever assembly(there are 5 different slots to choose from) but that made it only open about 1/8. Do I need to adjust the lever assemby's position on the governor crank post?
