Well I just finished cutting the crank on the engine to the same length as my old Pro.15 so it will fit in my Maxx. Cutting the crank wasn't as bad as I thought it would be. I just cut it long then used a grinding bit to finish the job. Anyways, I am looking at my instructions for the OS engine and it mentions setting the HSN at 2 turns then adjusting it 30 degrees for each tank of fuel that I run. It says that I should do this for at least 5 tanks of fuel. Sounds easy enough. However it does not make any mention of adjusting the LSN for the break-in. Am I to assume that means I don't need to adjust it at all? Right now the LSN is slightly indented from the housing.
