I just installed a new spark plug (the recommended plug) in a Honda
HRT16 lawn mower (bought at Home Depot). This plug was used once and
ran OK. The second time the mower sputtered and quit. When I checked
the plug, it was covered with heavy black carbon. I noticed this on two
previous plugs; once last summer and once the summer prior. Is the
mower running too rich? If so, how do I correct this? Any other
suggestions? Thanks.

Hi,
Checked air filter? Or oil level?

Thanks. The air filter is clean and the oil was changed Saturday.
Judging from what I read a few moments ago on another mower problem
thread (which I found right after posting this question), my mower is
running much too richly. Still, I don't know what the fix is?

Possibly l eaky carb float, engine flooding.

Adjust carb. Replace air filter.
