This applies to ALL engines: ESPECIALLY any 2-stroke engine (regardless of color or horsepower).

As for the next question.... it's important that the engine reach operating temperature after EACH engine startup. Again... Smartcraft is the BEST means of monitoring this (although 5 minutes is better than nothing... the engine may reach operating temp is considerably less time, OR- if thermostats are debris-laden, it may NEVER reach target temp).
