The thermostat on this engine is relatively easy to get at. But, you may have to move the ignition bracket. The screws never seem to get seized into that plastic housing.. Although the “vernatherm” inside usually fails open…
OK, my mistake, the overheat occurred at low speeds, which would explain why the engine didn’t seize and paint isn’t burnt.
Am guessing you shut the engine down when the horn went off and waited for it to cool. Did you remove the engine cover, did it seem overheated?
The plastic bag/weeds theory is still a possibility…
I’m assuming the engine didn’t overheat again when you restarted it…
