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 causes car to misfire at high speeds?
The spark timing might be too advanced. At high temperatures and RPM an advanced spark might cause preignition, and engine knock. That's only likely to happen if the engine is modified though. Other than that, check the air and fuel filters are clean, as the harder the engine has to work the more a clean flow of both is important.
