Hi, am having a problem with a Honda GCV 160. While running it seems as though the governor is not opening up quick enough, the mower dies for a second then picks up and runs properly. Happens any time I hit a bit of thick grass. Things I have done are reset coil gap, stripped and cleaned carby, reset valves, new spark plug, and checked timing which is alrite. Is it possible that a part of the internal governor mechanism is getting stuck for a second then picking up to were it should be.
