Technician: Curtis B., Technician replied 10 months ago

When it will not start, do you have spark? If you do, have you ever checked the valves for clearance? Engine needs .006 inch clearance intake and exhaust. If there is no clearnce, when hot, you will have negative clearance, and the valves leak, causing hard or no start.
