Reply To: Embarrassing Mistake

Checking the end gap is the first thing done when rebuilding a motor.

Unless the motor was bored out, chances are the sixty seven years of wear on the cylinders will allow new rings to be installed as is. I’ve never had to set the end gap yet when using original OMC/BRP rings but I do have to when using aftermarket rings such as NOS Perfect Circle brand.

If it was mine, I’d play it safe and tear it down again to be sure and laugh it off as a learning experience. I have enough trouble sleeping at night and having something like this on my mind wouldn’t help any.
