How do you adjust the valves on a White lawn tractor with a Briggs 14.5HP overhead valves?

Answer 1

There is an adjustment nut on the valve rockers underneath the valve covers

remove valve covers, and spark plugs, do one cylinder at a time, turn engine over by hand until top valve is completely pushed open, you can now adjust the lower"closed" valve, use a 13mm wrench and #30 torx, loosen jam nut use torx driver and set valve to .004 thousands with feeler guage, hold adjuster in place and tighten jam nut. recheck clearance, then rotate engine till lower valve opens completely and adjust top valve the same way, repeat on other cylinder, there is a good video on YouTube or go to www.smalleng

Answer 2

there is a plate that covers the valve springs , remover it, there should be a small nut type at the base of the valve , this will allow you to adjust the valve, setting, rotate the engine by HAND, till the valve is down, set intake at 30 thousands, exsuast at 30, On OHV engines, remove the spark plug and valve cover. turn the flywheel by hand until the piston is at top dead center (both valves closed). Continue turning until the piston is approx. 1/4" down into the cylinder bore. The intake valve is adjusted between .003"- .005" and the exhaust valve is adjusted between .005"- .007".
