Two Stroke Engine Break In
After engine has been installed and all fluids replenished (coolant/water, gear oil etc) you must then break the engine in properly. Improper break in results in lower reliability and possible engine seizures. Use the gas and oil mixture ratio that you intend to run after the break in. Check all fluid levels periodically during the break in. Check the carb jetting periodically during the break in.
