I honestly do NOT know how much to little clearance is on the crank counterweights confused
I shoot for .030+ on the rotating crank and rod parts on what I can see and measure, look and learn scope
A lot more clearance is way better than a tiny bit to little work luck
A good rotary hand grinder with good carbide bits is is your friend wrench
