Ran it for a good time with NO valve lash clearance. uh oh. NAPA can reface the valves and cut the seats for $25/ea but would have to remove and disassemble engine. Couple mower shops offered between $200-400 with engine installed. So I got the Neway LG-1000 Kit, which has 1/4, 5/16, 9/32, 8mm pilots, and the 124 cutter.
