I bought one of these to drain my pond
Trash Pump . It says a 2.4 hour run time, but mine would run about 6 hours. I put over 300 hours on it then sold it for more than I paid.
This one also has a honda clone engine, but many parts, like the carb are honda original, plus it's got a bigger engine for less money. Mine always satrted on the second pull, first pull was with the choke on.
