When I bought my predator 2000 for $449, I took it home, I pulled the spark plug and put about a teaspoon of oil in the hole and pulled the rope about 15 times to spread the oil around the cyclinder. I replaced the plug, put oil in as directed, about 13 OZ. The I put gas in. I pilled it twice and it started right up, It burned off the oil I put in the cyclinder, I ran it on
eco for an hour, dumped the oil and refilled it. Several hours later I ran it again for about an hour, this time I used full power and also used a 1500 watt heater for the last 15 minutes or so. Again dumped the oil and then added 13 OZ (approx.) and have used it several times, always starts on first pull. This is a good way to break any small engine in, you don't start on a dry cyclinder! I hope it lasts for me, if it doesn't give good service I will buy a Honda or Yamaha, maybe.
