I would have waited until it was ready to drive, hopefully its a roller cam and its not an issue with the springs or the break in. Also I would not reccomend starting it several time to move around the yard and in and out of the garage. It is critical, esspecially with a new build to get it warmed up fully when you start it. If you just start it to move it around, a minute here, a minute there, fuel will leak down through the cylinders and into your pan. Building up over time and cause ring and bearing wash with the large amount of fuel mixed with the oil and running down the cylinders. Push it if you can.
