Hi only went out for a couple of hours today.Will hit it harder tomorrow.Here is what I did find in my couple of hours. I do have a question with this one.The fins on this are larger and further apart from a normal power torque.Why? Also there is no decompression valve.The head has no hole at all for it.Dose anybody know why? This is for a Honda, catcher bag thingie.Does anybody need one? I have no use at all for this.I don't have a Honda.
