I have test run a new ryobi with very little time on it with bowman ,cd ignition 150 timing and found that it has a knock or looseness in the rod when it is flicked and also at slow rpm when running.
Is this normal until it develops more compression. I am running it in with mineral oil at 40:1 (Castrol2t) is this enough oil.
Mine is not this way
