Hello,

I have a new engine and after a few tanks through it i noticed that where the con rod connects to the crank shaft it was rubbing the rear removable part of the motor case.

Thought it was an easy fix, put some really thin washers on there in order to move it back just a little bit, I thought problem was solved.

But now it seems it has moved even more towards the rear and is rubbing the rear of the case even worse. so bad I can't run the motor.


What could cause this?
