I have had very good results running 100LL.... on my fourth season now and never a problem. It is easier to tune than some race gas and can make very good power. I highly recommend it.
Mike, Our dunes opened on April 1st and our weather has been so bad! TODAY will be my first run of the season, have the snipers on right now and should have time to make the switch in the next two weeks.
Yes, the damage is still visible, but the area was deburred by a professional engine builder. And according to that builder, the damage is in an area that will not affect anything.
