i use b8es i dont remember the gap, premix is personal preference as for ratios it depends on the oil most are 32:1 or 40:1, i use amsoil 100:1 mixed at 80:1.
I was at the hospital last night and there were 2 kids a gurney that were in a head on collision last weekend. I guess there friends dicided to have it there since they couldnt leave the hospital.
