All I did with a new OS .18 was start it on the bench and gave it a tiny throttle blip. I was then sure I'd be able to start it and run it when I got to the lake. Once at the lake, start it again, blip the throttle very slightly a few times and gave it a toss onto the water while throttleing up. Did a few laps varying throttle and brought it in before it ran out of gas. Filled it up and did it again. Repeat until heat cycling is complete. Then I tuned it for performance.
