suzuki 160 possible damage?

What could be the possible damage to my 160, if the gallery drain plug came out while running it? It still turns over(piston not froze). Thanks Bruce

Gallery drain plug? Do you mean the oil drain plug, that you use to drain oil from the motor or something else? If it ran without oil, the extent of the damage would depend on how long the motor was running without oil, and the only real way to asses the damage, would be to take the motor apart and inspect it visually. The first thing I would do is replace the plug, fill it with oil, and do a compression test. If the compression is low then you know there is a problem. If not, drain the oil into a clean container, and check for metal shavings in the oil. If the oil is clean, that is a good indication that the damage was minimal and you can re-use the oil.
