Shut it down and inspect it for any sort of leak, fuel ,oil and exhaust. Make sure that the choke is opening fully when the lever is in the full open position.#N#Some engines may take up to 50 hours or more of normal operation before they settle in and stabilize both fuel and oil consumption. During this time, I suggest following the manufacturers oil change recommendations and check oil levels periodically. Read and understand the procedures for correctly checking the engine oil level as this varies between engine types.#N#I also suggest using the manufacturers engine oil and filters while the engine is on warranty.#N#If the engine manufacturer allows for full synthetic engine oil, don't switch to it until after 50 or more hours are on the engine and the engine fuel and oil consumption has stabilized.#N#Just my thoughts!#N#Mad Mackie in CT:laughing::biggrin::smile:

What is engine break in?

The subject of engine break-in, if broadened to automotive and mobile equipment applications, can yield quite a range of opinions with regard to, one, whether it is even a valid concept, or two, just how you best accomplish your break-in period.# N#Given that engines on mowers have a service life spent primarily at governed speed, that eliminates many of the strategies that can apply to motor vehicles. At that point, break-in is simply a time period over which we have no control?#N#What is the thinking here with respect to how you handle break-in, if at all. What about synthetics? How long are you waiting to ensure ring seating before a possible switch to synthetics? Do you have favored multi-viscosity ratings? How often do you change oil and filter? Is there anything that you do to ensure a successful break-in period?#N#Discuss....#N#In my case, I am taking delivery soon of a machine powered by a 37 hp Kawasaki. In another thread on warranty coverage, it was mentioned that the Kawasaki program to double warranty if you use their oil.
