Frequently Asked Questions
What cup sizes are included in the two-stick valve lapping set?
One stick has 5/8 and 13/16-inch suction cups; the second has 1-1/8 and 1-3/8-inch cups, providing four valve-face contact sizes.
How is the correct valve lapping cup selected?
Use a clean cup smaller than the valve head that seals securely on a smooth valve face without overlapping the edge.
Can lapping repair a burned valve or badly recessed seat?
No. Deep pitting, burning, incorrect seat width or recession requires proper inspection and machining or replacement. Remove every trace of abrasive compound before engine assembly.
