Which is the least likely cause of an engine to hunt and surge at top no-load speeds?
The least likely cause of an engine hunting and surging at top no-load speeds is a fuel starvation issue. Typically, fuel starvation leads to a lean mixture, which would cause the engine to struggle or stall rather than hunt and surge. More common causes include issues with the governor system, air-fuel mixture adjustments, or ignition timing problems, which can directly affect engine performance at high speeds.
What will least likely to cause an engine to hunt and surge at top no load speeds?
The least likely cause of an engine hunting and surging at top no-load speeds is a malfunctioning fuel injector. Other factors such as an incorrect fuel-air mixture, vacuum leaks, or issues with the ignition system are more commonly associated with such symptoms. Fuel injectors typically affect engine performance under load, rather than at no-load conditions. Therefore, while they can influence overall engine behavior, they are less likely to be the primary cause of hunting and surging when the engine is not under load.

Can the linkage on a Briggs and stratton motor cause it to surge?
Yes, the linkage on a Briggs and Stratton motor can cause it to surge if it is misadjusted or damaged. This linkage controls the throttle and governor, which regulate the engine's speed and performance. If the linkage is sticking or not functioning properly, it can lead to inconsistent engine speeds, resulting in a surging effect. Regular maintenance and inspection of the linkage can help prevent this issue.
