    Jerry, Based on your comment – Typically how much clearance might be expected between the piston ring and the piston grooves? I used a .004 inch feeler through the exhaust ports. That fitted but a .006 inch feeler did not go.
    The motor started/ran/idled really well for the last couple of summers.
