A 12x6 is a little small. Maybe a 13x6. I run a 14x7 on my 75AX and that's what I broke it in with
Would you then suggest going straight to a 14x7 or first the 13x6 for break in period? The 12x6 even looks to small on that plane. It actually looks odd to be quite honest, it barely extends over the cowls edges. The reason for going 12x6 is because of the recommendation on the ASP "manual" which comes with the engine.
