I always copy my high octane spark table to my low octane just so the timing stays where i put it. imo bad gas could not cause that much kr. this is not directed twards you or anyone on here but why does everyone always talk about bad gas? what is bad gas? Like how is it different from regular gas? I think gas now a days has a pretty high q/a control on it. just my thoghts. i'v never had bad gas to my knowledge. good thinking though...it's probably the smallest that you and everybody else have over looked that is causing all of this lol.
