Replaced carb with brand new one from another machine, as well as fuel pump, gas is 1 day old. Engine still "hunts" under load. Is it pretty much narrowed down to the internal governor? Thanks.
^^^^ 99% of the time surging is cauzed by an air leak which creates a lean mix....anytime my kawi engines surge, i know its time to replace the intake manifold gaskets. usually get 2 years outa them before they disintegrate. The honda carb and others use thoses plastic spacers on the carbs that can crack also causing surging.......surging at full throttle, look for air leaks by spraying carb cleaner around carb and intake manifold gaskets, u will find the leak fast.
