What is the dumbest method to adjust valves on a single-cylinder gasoline engine?
1 Answers
First, open the valve cover and rotate the piston. When one valve is pushed down, it cannot be adjusted. After adjusting one, rotate the piston again, then adjust the other intake valve. Ensure the exhaust clearance on the opposite side exceeds 0.2 mm. Since the exhaust temperature is higher there causing expansion, adjust it to 0.3 mm.
