RE: Mechanical advance ignition
ronk1, I for one would be willing to pay more for a well broken in (used) gas engine - that I know the history on - than a brand new one that I had to put "gallons" of fuel thru hoping it was not involved in a crash before it got to max performance.
Dang, did I just type that, hope the next guy I buy a used gas motor from doesn't read this.
