Let it also cool down completely but every time one has to ensure that piston is at the bottom of the stroke at the time of cooling. It would be a good idea if the engine runs at 200 degree range during this period.

Next would be four more tanks running up to three-fourth throttle but the manner should be same as stated earlier. After this you one can go wide open and go in for another six tanks. These engines run best at 220 to 240 degrees plus a visible line of smoke should always be coming from the exhaust stinger.
