Some builders don’t hone the bore right. I’ve seen guys that just scratch it with a big spring loaded brake hone with no torque plates, don’t even measure and call it done. Loose as a goose because, as long as it doesn’t stick the piston they did a perfect job.

That being said, let us know what reading you get when you check it with open throttle.
