It means you read the instructions. Welcome to the Fox Club.

Yes a lot of people had trouble with the engines as they didn't read the instructions on how to break in the engines or how to adjust the carburetors. Then people became impatient and wanted engines they didn't have to break in too. So some brands started making  engines for them that didn't need to be broke in, but unfortunately that typically led to a engine that wore out faster. The some brands came up with the classic marketing strategy of having engines become obsolete faster and being a throwaway engine as well, as if they don't stock parts for them then you can't reapir or rebuild it, so you throw it away and get a new one. Or you make it cost prohibitive to repair it.
