Good thing for mechanic classes

First mechanical issue/non issue-
Symptom- One rickshaw isn’t hitting top speeds like past days this morning, and in fact going surprisingly slow for the easy road we were on.
Check- Air filter Spark plugs Motor heat Petrol levels Oil levels
Diagnosis- After pulling in a mechanic, the result is… nothing. He said it’s fine. 🤷🏽‍♀️
Moving on…
